• How to transform gameObjects in array?

  - by user1764781

  I have an array of available gameObjects in the scene. An array of GO should be transformed according to received floats through UDP connection. I know it is simple, but can't figure it out how to accomplish the transformation an array of GO according to received unique floats for each GO, any help will be appreciated. Here is a transformation floats, it might be helpful I guess: x =ReadSingleBigEndian(data, signalOffset); signalOffset+=4; y= ReadSingleBigEndian(data, signalOffset); signalOffset+=4; z= ReadSingleBigEndian(data, signalOffset); signalOffset+=4; alpha= ReadSingleBigEndian(data, signalOffset); signalOffset+=4; theta= ReadSingleBigEndian(data,signalOffset); signalOffset+=4; phi= ReadSingleBigEndian(data,signalOffset); signalOffset+=4;

• Turn-based JRPG battle system architecture resources

  - by BenoitRen

  The past months I've been busy programming a 2D JRPG (Japanese-style RPG) in C++ using the SDL library. The exploration mode is more or less done. Now I'm tackling the battle mode. I have been unable to find any resources about how a classic turn-based JRPG battle system is structured. All I find are discussions about damage formula. I've tried googling, searching gamedev.net's message board, and crawling through C++-related questions here on Stack Exchange. I've also tried reading source code of existing open source RPGs, but without a guide of some sort it's like trying to find a needle in a haystack. I'm not looking for a set of rules like D&D or anything similar. I'm talking purely about code and object structure design. A battle system asks the player for input using menus. Next the battle turn is executed as the heroes and the enemies execute their actions. Can anyone point me in the right direction? Thanks in advance.

• effect and model vertex declaration compatibility

  - by Vodácek

  I have normal model drawing code. When I try to draw model without UV coordinates I got this exception: System.InvalidOperationException: The current vertex declaration does not include all the elements required by the current vertex shader. TextureCoordinate0 is missing. at Microsoft.Xna.Framework.Graphics.GraphicsDevice.VerifyCanDraw( Boolean bUserPrimitives, Boolean bIndexedPrimitives) at Microsoft.Xna.Framework.Graphics.GraphicsDevice.DrawIndexedPrimitives( PrimitiveType primitiveType, Int32 baseVertex, Int32 minVertexIndex, Int32 numVertices, Int32 startIndex, Int32 primitiveCount) at Microsoft.Xna.Framework.Graphics.ModelMeshPart.Draw() at Microsoft.Xna.Framework.Graphics.ModelMesh.Draw() ... I know what cause the exception, but is possible to avoid it? Is possible to check model before drawing it with current shader for vertex declaration compatibility?

• text extraction from video game dialogue files [on hold]

  - by wdwvt1

  As part of an academic project, I am trying to access the dialogue files (whether audio or text) from a variety of sports video games (Madden or NBA 2kX would be fantastic). I have searched extensively on other sites (scholarly text-mining publications, r/gaming, r/madden, modding sites, etc.) for guidance in how to extract dialogue files, but have been unsuccessful. Given that I don't have even the domain specific language to ask the right question (i.e. the resources I am seeking are out there, I just can't find them) I am asking the SE game dev community for help with the 2 following questions: Is there a canonical resource that I should study that would get me started with how to extract text or audio files from games? I am very fluent in python, which usually excels at mining information from sources, but I struggle with knowing where to start with a video game (as opposed to a more familiar database with a defined API). Is this even feasible, or are protections included with newer games (e.g. NBA 2k13) going to make extraction of these resources in a programmatic way impossible? Thank you for your help!

• Curiosity on any Smartphones that Run on Android 2.3.3 with Different Screen Reoslution

  - by David Dimalanta

  I have a question regarding about any smartphones that run only in Android 2.3.3. Is the size of screen or the screen resolution is always HVGA or does it have capable of running this OS (Android 2.3.3) on big screen size (4" to 5") at about 720x1280? I'm thinking of the game's compatibility depending on the version of the Android OS and the screen resolution, which affects the change of coordinates especially for assigning touch buttons and drag-n-drop at exact location, before I'm gonna decide to make one. My program works on the Android 4 ICS and Jellybean, however, will that work on Android 2.3.3 in spite of precise touch coordinate or just dependent on the screen resolution (regardless how large it is) as the X and Y coordinate? And take note, I'm using Eclipse IDE for Java developers.

• Do leaderboard sets (in Game Center) allow 500 unique leaderboards?

  - by Korey Hinton

  The Game Kit Programming Guide for iOS claims: The number of different leaderboards allowed increases to 500 leaderboards per game when leaderboard sets have been enabled...Leaderboard sets offer developers the ability to combine several leaderboards into a single group. But their example (see image below) implies that a single leaderboard is placed into multiple leaderboard sets. Is that the only way to be able to use the full 500 leaderboards? by combining the same leaderboard into multiple sets? I want to be able to have 500 unique leaderboards that are not duplicated between sets. Is this possible?

• How to simulate pressure with particles?

  - by BeachRunnerJoe

  I'm trying to simulate pressure with a collection of spherical particles in a Unity game I'm building. A couple notes about the problem: The goal is to fill a constantly changing 2d space/void with small, frictionless spheres. The game is trying to simulate the ever-growing pressure of more objects being shoved into this space. The level itself is constantly scrolling from left to right, meaning if the space's dimensions are not changed by the user it will automatically get smaller (the leftmost part of the space will continually scroll off-screen). I'm wondering what some approaches are that I can take to tackling these problems... Knowing when to detect when there is space to fill and then add spheres to the space. Removing spheres from the space when it is shrinking. Strategies to simulate pressure on the spheres such that they "explode outwards" when more space is created. The current approach I am contemplating is using a constantly moving wall, that is off screen and moves with the screen, as this image illustrates: . This moving wall will push and trap the spheres into the space. As for adding new spheres, I was going to have either (1) spheres replicate themselves upon detecting free space, OR (2) spawn them at the left side of the space (where the wall is) - pushing the rest of the spheres to fill the space. I foresee problems with idea #1 because this likely wouldn't really create/simulate pressure; idea #2 seems more promising, but raises the question of how to provide a location for these new sphere particles to spawn (and the ramifications of spawning them when there IS no space). Thanks so much in advance for your wisdom!

• Pixel Collision - Detecting corners

  - by Milkboat

  How would I go about detecting the corners of a texture when I use pixel collision detection? I read about corner collision with rectangles, but I am unsure how to adapt it to my situation. Right now my map is tile based and I do rectangular collision until the player is intersecting with a blocked tile, then I switch to pixel collision. The effect I would like to achieve is when the player hits the corner of an object to push him around the side so he doesn't just hit the edge and stop. Any ideas?

• Using Lerp to create a hovering effect for a GameObject

  - by OhMrBigshot

  I want to have a GameObject that has a "hovering" effect when the mouse is over it. What I'm having trouble with is actually having a color that gradually goes from one color to the next. I'm assuming Color.Lerp() is the best function for that, but I can't seem to get it working properly. Here's my CubeBehavior.cs's Update() function: private bool ReachedTop = false; private float t = 0f; private float final_t; private bool MouseOver = false; // Update is called once per frame void Update () { if (MouseOver) { t = Time.time % 1f; // using Time.time to get a value between 0 and 1 if (t >= 1f || t <= 0f) // If it reaches either 0 or 1... ReachedTop = ReachedTop ? false : true; if (ReachedTop) final_t = 1f - t; // Make it count backwards else final_t = t; print (final_t); // for debugging purposes renderer.material.color = Color.Lerp(Color.red, Color.green, final_t); } } void OnMouseEnter() { MouseOver = true; } void OnMouseExit() { renderer.material.color = Color.white; MouseOver = false; } Now, I've tried several approaches to making it reach 1 then count backwards till 0 including a multiplier that alternates between 1 and -1, but I just can't seem to get that effect. The value goes to 1 then resets at 0. Any ideas on how to do this?

• What do you use to bundle / encrypt data?

  - by David McGraw

  More and more games are going the data driven route which means that there needs to be a layer of security around easy manipulation. I've seen it where games completely bundle up their assets (audio, art, data) and I'm wondering how they are managing that? Are there applications / libraries that will bundle and assist you with managing the assets within? If not is there any good resources that you would point to for packing / unpacking / encryption? This specific question revolves around C++, but I would be open to hear how this is managed in C#/XNA as well. Just to be clear -- I'm not out to engineer a solution to prevent hacking. At the fundamental level we're all manipulating 0's and 1's. But, we do want to keep the 99% of people that play the game from simply modifying XML files that are used to build the game world. I've seen plenty of games bundle all of their resources together. I'm simply curious about the methods they're using.

• Writing to a D3DFMT_R32F render target clamps to 1

  - by Mike

  I'm currently implementing a picking system. I render some objects in a frame buffer, which has a render target, which has the D3DFMT_R32F format. For each mesh, I set an integer constant evaluator, which is its material index. My shader is simple: I output the position of each vertex, and for each pixel, I cast the material index in float, and assign this value to the Red channel: int ObjectIndex; float4x4 WvpXf : WorldViewProjection< string UIWidget = "None"; >; struct VS_INPUT { float3 Position : POSITION; }; struct VS_OUTPUT { float4 Position : POSITION; }; struct PS_OUTPUT { float4 Color : COLOR0; }; VS_OUTPUT VSMain( const VS_INPUT input ) { VS_OUTPUT output = (VS_OUTPUT)0; output.Position = mul( float4(input.Position, 1), WvpXf ); return output; } PS_OUTPUT PSMain( const VS_OUTPUT input, in float2 vpos : VPOS ) { PS_OUTPUT output = (PS_OUTPUT)0; output.Color.r = float( ObjectIndex ); output.Color.gba = 0.0f; return output; } technique Default { pass P0 { VertexShader = compile vs_3_0 VSMain(); PixelShader = compile ps_3_0 PSMain(); } } The problem I have, is that somehow, the values written in the render target are clamped between 0.0f and 1.0f. I've tried to change the rendertarget format, but I always get clamped values... I don't know what the root of the problem is. For information, I have a depth render target attached to the frame buffer. I disabled the blend in the render state the stencil is disabled Any ideas?

• Is it possible to calculate or mathematically prove if a game is balanced / fair?

  - by Lurca

  This question is not focussed on video games but games in general. I went to a boardgame trade fair yesterday and asked myself if there is a way to calculate the fairness of a game. Sure, some of them require a good portion of luck, but it might be possible to calculate if some character is overpowered. Especially in role-playing games and trading card games. How, for example, can the creators of "Magic: The Gathering" make sure that there isn't the "one card that beats them all", given the impressive number of available cards?

• Are there any alternative JS ports of Box2D?

  - by Petteri Hietavirta

  I have been thinking about creating a top down 2D car game for HTML5. For my first game I wrote the physics and collisions my self but for this one I would like to use some ready made library. I found out Box2D and its JS port. http://box2d-js.sourceforge.net It seems to be quite old port, made in 2008. Is it lacking many features of current Box2D or does it have major issues with it? And are there any alternatives for it?

• MiniMax not working properly(for checkers game)

  - by engineer

  I am creating a checkers game but My miniMax is not functioning properly,it is always switching between two positions for its move(index 20 and 17).Here is my code: public double MiniMax(int[] board, int depth, int turn, int red_best, int black_best) { int source; int dest; double MAX_SCORE=-INFINITY,newScore; int MAX_DEPTH=3; int[] newBoard=new int[32]; generateMoves(board,turn); System.arraycopy(board, 0, newBoard, 0, 32); if(depth==MAX_DEPTH) { return Evaluation(turn,board);} for(int z=0;z<possibleMoves.size();z+=2){ source=Integer.parseInt(possibleMoves.elementAt(z).toString()); System.out.println("SOURCE= "+source); dest=Integer.parseInt(possibleMoves.elementAt(z+1).toString());//(int[])possibleMoves.elementAt(z+1); System.out.println("DEST = "+dest); applyMove(newBoard,source,dest); newScore=MiniMax(newBoard,depth+1,opponent(turn),red_best, black_best); if(newScore>MAX_SCORE) {MAX_SCORE=newScore;maxSource=source; maxDest=dest;}//maxSource and maxDest will be used to perform the move. if (MAX_SCORE > black_best) { if (MAX_SCORE >= red_best) break; /* alpha_beta cutoff */ else black_best = (int) MAX_SCORE; //the_score } if (MAX_SCORE < red_best) { if (MAX_SCORE<= black_best) break; /* alpha_beta cutoff */ else red_best = (int) MAX_SCORE; //the_score } }//for ends return MAX_SCORE; } //end minimax I am unable to find out the logical mistake. Any idea what's going wrong?

• How to give a ball a following texture trailing effect

  - by Evan Kohilas

  How do I draw copies of the leading texture so that there is a line of the leading ball following behind it? (that don't collide) So far I have tried to create the effect by placing another graphic 2 pixels off the graphic, but I don't see the second ball being drawn. spriteBatch.Draw(ballTexture, ballPos, null, Color.White, 0.0f, new Vector2(Ballpos.X +2, ballPos.Y +2), ballSize, SpriteEffects.None, 0); Thanks.

• I need to move an entity to the mouse location after i rightclick

  - by I.Hristov

  Well I've read the related questions-answers but still cant find a way to move my champion to the mouse position after a right-button mouse-click. I use this code at the top: float speed = (float)1/3; And this is in my void Update: //check if right mouse button is clicked if (mouse.RightButton == ButtonState.Released && previousButtonState == ButtonState.Pressed) { // gets the position of the mouse in mousePosition mousePosition = new Vector2(mouse.X, mouse.Y); //gets the current position of champion (the drawRectangle) currentChampionPosition = new Vector2(drawRectangle.X, drawRectangle.Y); // move champion to mouse position: //handles the case when the mouse position is really close to current position if (Math.Abs(currentChampionPosition.X - mousePosition.X) <= speed && Math.Abs(currentChampionPosition.Y - mousePosition.Y) <= speed) { drawRectangle.X = (int)mousePosition.X; drawRectangle.Y = (int)mousePosition.Y; } else if (currentChampionPosition != mousePosition) { drawRectangle.X += (int)((mousePosition.X - currentChampionPosition.X) * speed); drawRectangle.Y += (int)((mousePosition.Y - currentChampionPosition.Y) * speed); } } previousButtonState = mouse.RightButton; What that code does at the moment is on a click it brings the sprite 1/3 of the distance to the mouse but only once. How do I make it move consistently all the time? It seems I am not updating the sprite at all. EDIT I added the Vector2 as Nick said and with speed changed to 50 it should be OK. I tried it with if ButtonState.Pressed and it works while pressing the button. Thanks. However I wanted it to start moving when single mouse clicked. It should be moving until reaches the mousePosition. The Edit of Nick's post says to create another Vector2, But I already have the one called mousePosition. Not sure how to use another one. //gets a Vector2 direction to move *by Nick Wilson Vector2 direction = mousePosition - currentChampionPosition; //make the direction vector a unit vector direction.Normalize(); //multiply with speed (number of pixels) direction *= speed; // move champion to mouse position if (currentChampionPosition != mousePosition) { drawRectangle.X += (int)(direction.X); drawRectangle.Y += (int)(direction.Y); } } previousButtonState = mouse.RightButton;

• 2D Grid Map Connectivity Check (avoiding stack overflow)

  - by SombreErmine

  I am trying to create a routine in C++ that will run before a more expensive A* algorithm that checks to see if two nodes on a 2D grid map are connected or not. What I need to know is a good way to accomplish this sequentially rather than recursively to avoid overflowing the stack. What I've Done Already I've implemented this with ease using a recursive algorithm; however, depending upon different situations it will generate a stack overflow. Upon researching this, I've come to the conclusion that it is overflowing the stack because of too many recursive function calls. I am sure that my recursion does not enter an infinite loop. I generate connected sets at the beginning of the level, and then I use those connected sets to determine connectivity on the fly later. Basically, the generating algorithm starts from left-to-right top-to-bottom. It skips wall nodes and marks them as visited. Whenever it reaches a walkable node, it recursively checks in all four cardinal directions for connected walkable nodes. Every node that gets checked is marked as visited so they aren't handled twice. After checking a node, it is added to either a walls set, a doors set, or one of multiple walkable nodes sets. Once it fills that area, it continues the original ltr ttb loop skipping already-visited nodes. I've also looked into flood-fill algorithms, but I can't make sense of the sequential algorithms and how to adapt them. Can anyone suggest a better way to accomplish this without causing a stack overflow? The only way I can think of is to do the left-to-right top-to-bottom loop generating connected sets on a row basis. Then check the previous row to see if any of the connected sets are connected and then join the sets that are. I haven't decided on the best data structures to use for that though. I also just thought about having the connected sets pre-generated outside the game, but I wouldn't know where to start with creating a tool for that. Any help is appreciated. Thanks!

• How do I check on non-transparent pixels in a bitmapdata?

  - by Opoe

  I'm still working on my window cleaning game from one of my previous questions I marked a contribution as my answer, but after all this time I can't get it to work and I have to many questions about this so I decided to ask some more about it. As a sequel on my mentioned previous question, my question to you is: How can I check whether or not a bitmapData contains non transparent pixels? Subquestion: Is this possible when the masked image is a movieclip? Shouldn't I use graphics instead? Information I have: A dirtywindow movieclip on the bottom layer and a clean window movieclip on layer 2(mc1) on the layer above. To hide the top layer(the dirty window) I assign a mask to it. Code // this creates a mask that hides the movieclip on top var mask_mc:MovieClip = new MovieClip(); addChild(mask_mc) //assign the mask to the movieclip it should 'cover' mc1.mask = mask_mc; With a brush(cursor) the player wipes of the dirt ( actualy setting the fill from the mask to transparent so the clean window appears) //add event listeners for the 'brush' brush_mc.addEventListener(MouseEvent.MOUSE_DOWN,brushDown); brush_mc.addEventListener(MouseEvent.MOUSE_UP,brushUp); //function to drag the brush over the mask function brushDown(dragging:MouseEvent):void{ dragging.currentTarget.startDrag(); MovieClip(dragging.currentTarget).addEventListener(Event.ENTER_FRAME,erase) ; mask_mc.graphics.moveTo(brush_mc.x,brush_mc.y); } //function to stop dragging the brush over the mask function brushUp(dragging:MouseEvent):void{ dragging.currentTarget.stopDrag(); MovieClip(dragging.currentTarget).removeEventListener(Event.ENTER_FRAME,erase); } //fill the mask with transparant pixels so the movieclip turns visible function erase(e:Event):void{ with(mask_mc.graphics){ beginFill(0x000000); drawRect(brush_mc.x,brush_mc.y,brush_mc.width,brush_mc.height); endFill(); } }

• How can I handle copyrighted music?

  - by David Dimalanta

  I have a curious question regarding on musics used in music rhythm game. In Guitar Hero for example, they used all different music albums in one program. Then, each album requires to ask permission to the owner, composer of the music, or the copyright owner of the music. Let's say, if you used 15 albums for the music rhythm game, then you have to contact 15 copyright owners and it might be that, for the game developer, that the profit earned goes to the copyright owner or owner of this music. For the independent game developers, was it okay if either used the copyright music by just mentioning the name of the singer included in the credits and in the music select screen or use the non-popular/old music that about 50 years ago? And, does still earn money for the indie game developers by making free downloadable game?

• the unity aspect ratio script looks good in computer but not in android phones

  - by Pooya Fayyaz

  I'm developing a game for android devices.and i have a script that solve the ratio problem but i have a problem in this code.and i dont know why.it looks perfect in computer even resize the game screen but in mobile phones have a problem.my game runs in landscape mode.this is the script : using UnityEngine; using System.Collections; using System.Collections.Generic; public class reso : MonoBehaviour { void Update() { // set the desired aspect ratio (the values in this example are // hard-coded for 16:9, but you could make them into public // variables instead so you can set them at design time) float targetaspect = 16.0f / 9.0f; // determine the game window's current aspect ratio float windowaspect = (float)Screen.width / (float)Screen.height; // current viewport height should be scaled by this amount float scaleheight = windowaspect / targetaspect; // obtain camera component so we can modify its viewport Camera camera = GetComponent<Camera>(); // if scaled height is less than current height, add letterbox if (scaleheight < 1.0f && Screen.width <= 490 ) { Rect rect = camera.rect; rect.width = 1.0f; rect.height = scaleheight; rect.x = 0; rect.y = (1.0f - scaleheight) / 2.0f; camera.rect = rect; } else // add pillarbox { float scalewidth = 1.0f / scaleheight; Rect rect = camera.rect; rect.width = scalewidth; rect.height = 1.0f; rect.x = (1.0f - scalewidth) / 2.0f; rect.y = 0; camera.rect = rect; } } } i figure that my problem occur in this part of the script: if (scaleheight < 1.0f) { Rect rect = camera.rect; rect.width = 1.0f; rect.height = scaleheight; rect.x = 0; rect.y = (1.0f - scaleheight) / 2.0f; camera.rect = rect; } and its look like this in my mobile phone in portrait: and in landscape mode:

• How do I adjust the origin of rotation for a group of sprites?

  - by Jon

  I am currently grouping sprites together, then applying a rotation transformation on draw: private void UpdateMatrix(ref Vector2 origin, float radians) { Vector3 matrixorigin = new Vector3(origin, 0); _rotationMatrix = Matrix.CreateTranslation(-matrixorigin) * Matrix.CreateRotationZ(radians) * Matrix.CreateTranslation(matrixorigin); } Where the origin is the Centermost point of my group of sprites. I apply this transformation to each sprite in the group. My problem is that when I adjust the point of origin, my entire sprite group will re-position itself on screen. How could I differentiate the point of rotation used in the transformation, from the position of the sprite group? Is there a better way of creating this transformation matrix? EDIT Here is the relevant part of the Draw() function: Matrix allTransforms = _rotationMatrix * camera.GetTransformation(); spriteBatch.Begin(SpriteSortMode.BackToFront, null, null, null, null, null, allTransforms); for (int i = 0; i < _map.AllParts.Count; i++) { for (int j = 0; j < _map.AllParts[0].Count; j++) { spriteBatch.Draw(_map.AllParts[i][j].Texture, _map.AllParts[i][j].Position, null, Color.White, 0, _map.AllParts[i][j].Origin, 1.0f, SpriteEffects.None, 0f); } } This all works fine, again, the problem is that when a rotation is set and the point of origin is changed, the sprite group's position is offset on screen. I am trying to figure out a way to adjust the point of origin without causing a shift in position. EDIT 2 At this point, I'm looking for workarounds as this is not working. Does anyone know of a better way to rotate a group of sprites in XNA? I need a method that will allow me to modify the point of rotation (origin) without affecting the position of the sprite group on screen.

• How does Starcraft 2 load it's metadata?

  - by chobok

  Lets say you are playing Starcraft 2 melee map. The game loads the map. Melee maps have the following dependencies: Liberty (Mod) Liberty Multi (Mod) I think the game engine will load the data from Liberty (Mod) first, then from Liberty Multi (Mod). For data that exists in both dependencies, the engine will use the one from Liberty Multi (Mod). Is this correct? Liberty Multi (Mod) is updated with each patch of Starcraft 2. Does the game engine load just the latest version of Liberty Multi (Mod)? or Does the game engine load all the versions and overwrite duplicate data with the latest version?

• Group Matchmaking

  - by Simon Kérouack

  Consider different groups(1 or more players) queuing together, we want to make 2 opposing teams containing each the same amount of players while keeping the groups together. At the same time we want to make both teams' average ranking as close as possible. Now also consider we have as a working set the subset of groups currently queuing within a given ranking range. For an example, let's say we have the following groups, ordered by queuing time: Id, playerCount, totalRank, avgRank 0, 3, 126, 42 1, 2, 60, 30 2, 1, 25, 25 3, 2, 80, 40 4, 1, 40, 40 5, 1, 20, 20 6, 3, 150, 50 for this specific subset, the expected output should ideally be: team1: 0, 1 (total: 186) team2: 2, 5, 6 (total: 195) up to now the solution I have been using is to balance out each team by making each team pick the group with highest ranking within the subset turn by turn. The team who picks is the one with the currently lowest average rank unless one is already full. If one team is already full the other team tries to complete itself with groups that would make the rank gap as small as possible. This solution turns out to have issues with frequent edge cases and I'm looking for a better solution, or some fine-tuning that could be made. In most cases, players seems to want teams of 5 people and queue in group of 2. Our average subset when 2 teams of 5 are chosen is made of about 14 players if that may be of any help.

• Understanding how texCUBE works and writing cubemaps properly into a cube rendertarget

  - by cubrman

  My goal is to create accurate reflections, sampled from a dynamic cubemap, for specific 3d objects (mostly lights) in XNA 4.0. To sample the cubemap I compute the 3d reflection vector in a classic way: half3 ReflectionVec = reflect(-directionToCamera, Normal.rgb); I then use the vector to get the actual reflected color: half3 ReflectionCol = texCUBElod(ReflectionSampler, float4(ReflectionVec, 0)); The cubemap I am sampling from is a RenderTarget with 6 flat faces. So my question is, given the 3d world position of an arbitrary 3d object, how can I make sure that I get accurate reflections of this object, when I re-render the cubemap. Should I build the ViewProjection matrix in a specific way? Or is there any other approach?
