• How to offset particles from point of origin

  - by Sun

  Hi I'm having troubles off setting particles from a point of origin. I want my particles to spread out after a certain radius from a the point of origin. For example, this is what I have right now: All particles emitted from a point of origin. What I want is this: Particles are offset from the point of origin by some amount, i.e after the circle. What is the best way to achieve this? At the moment, I have the point of origin, the position of each particle and its rotation angle. Sorry for the poor illustrations. Edit: I was mistaken, when a particle is created, I have only the point of origin. When the particle is created I am able to calculate the rotation of the particle in the update method after it has moved to a new location using atan2() method. This is how I create/manage particles: Created new particle at enemy ship death location, for every new particle which is added to the list, call Update and Draw to update its position, calculate new angle and draw it.

• Syntax error in Maya Python Script [on hold]

  - by Enchanter

  Ok this error is immensly frustrating as it is obviously a simple syntax issue. Basically I've written two lines of maya script in python designed to create a list of the names of all the joints of a model currently selected in the model viewer. Here are the two lines of script: import maya.cmds joints = ls(selection = true, type = 'joint') Upon compiling the code the script editor is saying there is a syntax error in the second line, but I do not see any reason why this code should not execute?

• Problem with gluOrtho2D()

  - by Shashwat

  I was trying to understand the gluOrtho2D function. I have drawn 4 lines originating from the center reaching up to 4 corners of the screen. You can follow the below code. osize is a variable which is used to set the parameters of gluOrtho2D. It will create a window of size 2*osize. If works fine when osize is 1. Lines reach the corners. But as I increase the value of osize, the length of the lines decreases (cross becomes smaller and does not cover the whole screen). But I think it should reach the corner. void display() { glClear( GL_COLOR_BUFFER_BIT ); //glViewport(0, 0, 100, 100); glMatrixMode (GL_PROJECTION); float osize = 1.2; //glOrtho(-osize*1.0, osize*1.0, osize*1.0, -osize*1.0, -1.0, 1.0); gluOrtho2D(-osize*1.0, osize*1.0, osize*1.0, -osize*1.0); glMatrixMode (GL_MODELVIEW); glBegin(GL_LINES); glColor3f(0.0, 0.0, 1.0); glVertex2f(0.0, 0.0); glVertex2f(-osize*1.0, -osize*1.0); glVertex2f(0.0, 0.0); glVertex2f(-osize*1.0, osize*1.0); glVertex2f(0.0, 0.0); glVertex2f(osize*1.0, -osize*1.0); glVertex2f(0.0, 0.0); glVertex2f(osize*1.0, osize*1.0); glEnd(); glutSwapBuffers(); //includes glFlush(); } What is the problem?

• Getting Started with Component Architecture: DI?

  - by ashes999

  I just moved away from MVC towards something more component-architecture-like. I have no concept of messages yet (it's rough prototype code), objects just get internal properties and values of other classes for now. That issue aside, it seems like this is turning into an aspect-oriented-programming challenge. I've noticed that all entities with, for example, a position component will have similar properties (get/set X/Y/Z, rotation, velocity). Is it a common practice, and/or good idea, to push these behind an interface and use dependency injection to inject a generic class (eg. PositionComponent) which already has all the boiler-plate code? (I'm sure the answer will affect the model I use for message/passing)

• ArrayList of Entites Random Movement

  - by opiop65

  I have an arraylist of entites that I want to move randomly. No matter what I do, they won't move. Here is my female class: import java.awt.Graphics2D; import java.awt.Image; import java.awt.Rectangle; import java.util.Random; import javax.swing.ImageIcon; public class Female extends Entity { static int femaleX = 0; static int femaleY = 0; double walkSpeed = .1f; Random rand = new Random(); int random; int dir; Player player; public Female(int posX, int posY) { super(posX, posY); } public void update() { posX += femaleX; posY += femaleY; } public void draw(Graphics2D g2d) { g2d.drawImage(getFemaleImg(), posX, posY, null); if (Player.showBounds == true) { g2d.draw(getBounds()); } } public Image getFemaleImg() { ImageIcon ic = new ImageIcon("res/female.png"); return ic.getImage(); } public Rectangle getBounds() { return new Rectangle(posX, posY, getFemaleImg().getHeight(null), getFemaleImg().getWidth(null)); } public void moveFemale() { random = rand.nextInt(3); System.out.println(random); if (random == 0) { dir = 0; posX -= (int) walkSpeed; } } } And here is how I update the female class in the main class: public void actionPerformed(ActionEvent ae) { player.update(); for(int i = 0; i < females.size(); i++){ Female tempFemale = females.get(i); tempFemale.update(); } repaint(); } If I do something like this(in the female update method): public void update() { posX += femaleX; posY += femaleY; posX -= walkSpeed; } The characters move with no problem. Why is this?

• How to stop reducing life? [closed]

  CODE Input input = gc.getInput(); int xpos = Mouse.getX(); int ypos = Mouse.getY(); emu = "Enemy Life : " + enemyLife; Life = "Your Life Is" + life; Mousepos = "X:" + xpos + "Y:" + ypos; //test test1 = "Test INT" + test1int; if(!repeatStop) { //if this button is press, the damage will add up. When //pressed fight, it would start reducing the enemy health. if(input.isKeyPressed(Input.KEY_1)) { test1int += 1; } } if((xpos>1007 &xpos<1297)&&(ypos>881 && ypos<971)) { //Fight button if(Mouse.isButtonDown(0)){ finishTurn=true; } } //fight has started if(finishTurn==true) { //this would reduce the enemy life if(floodControl1==false) { enemyLife-=test1int; } //PROBLEM: Does not stop reducing! //the below code was not successful. It did not stop it // from reducing further. if(test1int>10) { floodControl1=true; } } QUESTION: Ok now, this is what is does. When I press the key, 1, it adds up the damage to the enemy. When I press fight, It will then start to reduce the enemy's health. Now my problem is, it kept on reducing and deducting it until negative! How do I deduct it to my desired damage (My desired damage is the one when press key 1)?

• How do I create a fire sphere (fireball) in opengl? (opengl Visual C++)

  - by gn66

  I'm making an evil Pacman in OpenGL and I need to make my spheres look like a fireballs, does anyone know how I do that? And what material colour should I use? Also, is there a colour palette to change the colour of my materials? This is how I create a sphere: GLfloat mat_ambient[] = { 0.25, 0.25, 0.25, 1.0 }; GLfloat mat_diffuse[] = { 0.4, 0.4, 0.4, 1.0 }; GLfloat mat_specular[] = { 0.774597, 0.774597, 0.774597, 1.0 }; GLfloat mat_shine = 0.6; glMaterialfv (GL_FRONT, GL_AMBIENT, mat_ambient); glMaterialfv (GL_FRONT, GL_DIFFUSE, mat_diffuse); glMaterialfv (GL_FRONT, GL_SPECULAR, mat_specular); glMaterialf (GL_FRONT, GL_SHININESS, mat_shine * 128); glPushMatrix(); glTranslatef(x,y,0); glutSolidSphere(size, 20, 10); glFlush(); glPopMatrix();

• Enabling and Disabling Colliders Unity

  - by Blue

  I'm trying to make the collider appear every 1 second. But I can't get the code write. I tried enabling the collider under a boolean and putting a yield to make it every second or so. But it's not working(gives me an error: Update() can not be a coroutine.). How would I fix this? Would I need a timer system and set the collider to be enabled every 'x' seconds and disabled every 'y' seconds? var waitTime : float = 1; var trigger : boolean = false; function Update () { if(!trigger){ collider.enabled = false; yield WaitForSeconds(waitTime); } if(trigger){ collider.enabled = true; yield WaitForSeconds(waitTime); } } }

• Using Bullet physics engine to find the moment of object contact before penetration

  - by MooMoo

  I would like to use Bullet Physics engine to simulate the objects in 3D world. One of the objects in the world will move using the position from 3D mouse control. I will call it "Mouse Object" and any object in the world as "Object A" I define the time before "mouse object" and "Object A" collide as t-1 The time "mouse object" penetrate "Object A" as t Now there is a problem about rendering the scene because when I move the mouse very fast, "Mouse object" will reside in "Object A" before "Object A" start to move. I would like the "Mouse Object" to stop right away attach to the "Object A". Also If the "Object A" move, the "Mouse object" should move following (attach) the "Object A" without stop at the first collision take place. This is what i did I find the position of the "Mouse Object" at time t-1 and time t. I will name it as pos(t-1) and pos(t) The contact time will be sometime between t-1 to t, which the time of contact I name it as t_contact, therefore the contact position (without penetration) between "Mouse object" and "Object A" will be pos(t_contact) then I create multiple "Mouse object"s using this equation pos[n] = pos(t-1) * C * ( pos(t) - pos(t-1) ) where 0 <= C <= 1 if I choose C = 0.1, 0.2, 0.3,0.4..... 1.0, I will get pos[n] for 10 values Then I test collision for all of these 10 "Mouse Objects" and choose the one that seperate between "no collision" and "collision". I feel this method is super non-efficient. I am not sure the way other people find the time-of-contact or the position-of-contact when "Object A" can move.

• Determining if something is on the right or left side of an object?

  - by meds

  I have a character in a 3D world which is facing an arbitrary direction on a flat plane, the player can click on the left or right side of the character and based on which side is clicked on a different action happens. How can I determine which side the click occured on? Obviously for straight on ahead (0,0,1) I can simply use the x coordinate of the click point to determine if it's the left or right hand side, but what about other cases?

• Modular building technique with angles? (A roof)

  - by Mungoid

  Ive been spending a bit of time lately studying the modular buildings of many games and reading/viewing several tutorials about it as well, but almost every example I see uses a plain square building that does not have any angled roof or similar. In all my applications (CS6, Blender/Max, UDK) I adhere to the same grid spacing and I get pretty good results, but trying to make modular angled pieces is confusing me as I'm not sure the best way to approach it. Below is some shots of my template sheet and workflow I have been doing. Should I do the roof separately or is it possible for me to keep it in the same texture sheet? The main issue is below. I have made a couple modular roof pieces but when i try to use them, i end up needing to model multiple other parts to fill gaps based on what roof shape i want. I then model those 'filler' pieces and now i have that much less space left in my texture sheet and those pieces are usually not that reusable for anything else. This is where im not sure how to proceed. If anyone has any links to documents or papers talking about this or advice, I would greatly appreciate it! =-) My main roof pieces with the gaps My power of 2 texture sheet, with 16x16 grid squares. The texture sheet loaded into blender on a 16x16 plane and starting to separate and extrude.

• What is the correct way to use glTexCoordPointer?

  - by RubyKing

  I'm trying to work out how to use this function glTexCoordPointer. The man page states that I must set a pointer to the first element of the array that uses the texture cordinate. Here is my array: static const GLfloat GUIVertices[] = { //FIRST QUAD 1.0f, 1.0f, 0.0f, 1.0f, 1.0f, 0.0f, -1.0f, 1.0f, 0.0f, 1.0f, 0.0f, 0.0f, -1.0f, 0.94f, 0.0f, 1.0f, 0.0f, 1.0f, 1.0f, 0.94f, 0.0f, 1.0f, 1.0f, 1.0f, //2ND QUAD // x y z w X Y 1.0f, -1.0f, 0.0f, 1.0f, 1.0f, 0.0f, -1.0f, -1.0f, 0.0f, 1.0f, 0.0f, 0.0f, -1.0f, -0.94f, 0.0f, 1.0f, 0.0f, 1.0f, 1.0f, -0.94f, 0.0f, 1.0f, 1.0f, 1.0, }; But how do I set the pointer correctly for the fifth element on the 2nd quad first row? I was thinking something like this: glTexCoordPointer(1, GL_FLOAT, 6, reinterpret_cast<const GLvoid *>(29 * sizeof(float)));

• How are dependant quests generated in Guild Wars 2?

  - by Aufziehvogel

  I recently read that Guild Wars 2 uses a system where the creation of quests depends on which actions user took when they were presented another quest. An example was: There might be a quest to protect a person. If users do not take this action, the person might be kidnapped and later there is a quest to rescue this person. Is there any information on whether the creation of these quests is somehow automatic? From the article it sounded like automatically, but from the specific example you could also guess that people just created a task-set where they added conditions (Task 1 taken: OK; Task 1 not taken: Show Task 2). From what I heard about AI they might also have implemented some sort of a huge neural network to make decisions?

• How do 2D physics engines solve the problem of resolving collisions along tiled walls/floors in non-grid-based worlds?

  - by ssb

  I've been working on implementing my SAT algorithm which has been coming along well, but I've found that I'm at a wall when it comes to its actual use. There are plenty of questions regarding this issue on this site, but most of them either have no clear, good answer or have a solution based on checking grid positions. To restate the problem that I and many others are having, if you have a tiled surface, like a wall or a floor, consisting of several smaller component rectangles, and you traverse along them with another rectangle with force being applied into that structure, there are cases where the object gets caught on a false collision on an edge that faces the inside of the shape. I have spent a lot of time thinking about how I could possibly solve this without having to resort to a grid-based system, and I realized that physics engines do this properly. What I want to know is how they do this. What do physics engines do beyond basic SAT that allows this kind of proper collision resolution in complex environments? I've been looking through the source code to Box2D trying to find out how they do it but it's not quite as easy as looking at a Collision() method. I think I'm not good enough at physics to know what they're doing mathematically and not good enough at programming to know what they're doing programmatically. This is what I aim to fix.

• How can I perform a masked erase in SDL2?

  - by Kvisle

  I'm trying to implement some shadow/lighting effects in my 2D-project, and I've concluded that if there is an easy way to perform a masked erase on an SDL_Texture, it would make the drawing operations quite cheap. Let's say I have a texture of the part of the level where light is not meant to be rendered. I also have a texture with my "light map"; I want to use this to just draw omni lights from my light sources. Then I want to use the first image to 'subtract' the portions of the light map that are not to be rendered on the final scene. Then I draw my "light map" texture on top of my scene, with additive blending enabled. This sounds like a good theory in my head, but I can't see any functions in the SDL2 API that let me do masked erase from a texture. Am I overlooking something? Does anything like this exist?

• Keyboard is not detecting as3

• How do I implement deceleration for the player character?

  - by tesselode

  Using delta time with addition and subtraction is easy. player.speed += 100 * dt However, multiplication and division complicate things a bit. For example, let's say I want the player to double his speed every second. player.speed = player.speed * 2 * dt I can't do this because it'll slow down the player (unless delta time is really high). Division is the same way, except it'll speed things way up. How can I handle multiplication and division with delta time? Edit: it looks like my question has confused everyone. I really just wanted to be able to implement deceleration without this horrible mass of code: else if speed > 0 then speed = speed - 20 * dt if speed < 0 then speed = 0 end end if speed < 0 then speed = speed + 20 * dt if speed > 0 then speed = 0 end end end Because that's way bigger than it needs to be. So far a better solution seems to be: speed = speed - speed * whatever_number * dt

• Keeping the meshes "thickness" the same when scaling an object

  - by user1806687

  I've been bashing my head for the past couple of weeks trying to find a way to help me accomplish, on first look very easy task. So, I got this one object currently made out of 5 cuboids (2 sides, 1 top, 1 bottom, 1 back), this is just for an example, later on there will be whole range of different set ups. Now, the thing is when the user chooses to scale the whole object this is what should happen: X scale: top and bottom cuboids should get scaled by a scale factor, sides should get moved so they are positioned just like they were before(in this case at both ends of top and bottom cuboids), back should get scaled so it fits like before(if I simply scale it by a scale factor it will leave gaps on each side). Y scale: sides should get scaled by a scale factor, top and bottom cuboid should get moved, and back should also get scaled. Z scale: sides, top and bottom cuboids should get scaled, back should get moved. Hope you can help, EDIT: So, I've decided to explain the situation once more, this time more detailed(hopefully). I've also made some pictures of how the scaling should look like, where is the problem and the wrong way of scaling. I this example I will be using a thick walled box, with one face missing, where each wall is made by a cuboid(but later on there will be diffrent shapes of objects, where a one of the face might be roundish, or triangle or even under some angle), scaling will be 2x on X axis. 1.This is how the default object without any scaling applied looks like: http://img856.imageshack.us/img856/4293/defaulttz.png 2.If I scale the whole object(all of the meshes) by some scale factor, the problem becomes that the "thickness" of the object walls also change(which I do not want): http://img822.imageshack.us/img822/9073/wrongwaytoscale.png 3.This is how the correct scaling should look like. Appropriate faces gets caled in this case where the scale is on X axis(top, bottom, back): http://imageshack.us/photo/my-images/163/rightwayxscale1.png/ 4.But the scale factor might not be the same for all object all of the times. In this case the back has to get scaled a bit more or it leaves gaps: http://imageshack.us/photo/my-images/9/problemwhenscaling.png/ 5.If everything goes well this is how the final object should look like: http://imageshack.us/photo/my-images/856/rightwayxscale2.png/ So, as you have might noticed there are quite a bit of things to look out when scaling. I am asking you, if any of you have any idea on how to accomplish this scaling. I have tried whole bunch of things, from scaling all of the object by the same scale factor, to subtracting and adding sizes to get the right size. But nothing I tried worked, if one mesh got scaled correctly then others didnt. Donwload the example object. English is not my first language, so I am really sorry if its hard to understand what I am saying.

• Vector reflect problem

  - by xdevel2000

  I'm testing some vector reflection and I want to check what happens when a ball collides with a paddle. So if I have: Vector2 velocity = new Vector2(-5, 2); position_ball += velocity; if (position_ball.X < 10) { Vector2 v = new Vector2(1,0); // or Vector2.UnitX velocity = Vector2.Reflect(velocity, v); } then, correctly, velocity is (5,2) after Reflect, but if I do: if (position_ball.X < 10) { Vector2 v = new Vector2(1,1); velocity = Vector2.Reflect(velocity, v); } then velocity is (1,8) and not (5, -2) that is the solution of reflection equation R = V - 2 * (V . N) Why is that?

• Handling hitboxes

  - by TheBroodian

  So I have an issue that I'm laughing at myself about, because it really seems like it should be something that I should be able to figure out pretty quickly. I am designing a 2D action platformer; I have a playable character, and a dummy 'punching bag' character for testing purposes that I've created. I've just gotten enough of both of them done that I can start prototyping and testing them in runtime. Then I realized- neither of them have references of each other (intentionally so), so how do I check for hitboxes stored within my playable character from my dummy character? Long story short, how do I make my dummy know when he's been punched by my hero?

• forward rendering and multiple shadow maps

  - by Irbis

  I have two light sources on my scene. I created two fbo's which store depth textures for these lights. A render loop looks like this: bind fbo1 save depth values for first light unbind fbo1 bind fbo2 save depth values for second light unbind fbo2 enable additive blending bind first depth texture render scene bind second depth texture render scene disable additive blending For one light source the program works fine. For many light sources I use an additive blending to acumulate lighting results but then some objects become transparent (for example when an object which is further away from the camera is drawn before an object which is closer to the camera). How to resolve that problem ? How should I accumulate lighting effects for many light sources (many shadow maps) ? P.S. I use OpenGL/GLSL 3.3+

• Certain grid lines not rendering as expected

  - by row1

  I am drawing a simple quad (a triangle strip with 4 vertices) as the floor and then drawing an 8x8 grid over top (a collection of vertex pairs for a line list). The vertical grid lines work fine (apart from being very aliased), but some of the horizontal lines do not get rendered. The grid renders fine if I do not draw the quad. foreach (EffectPass pass in _Effect.CurrentTechnique.Passes) { pass.Apply(); CurrentGraphicsDevice.SetVertexBuffer(_VertexFloorBuffer); _Engine.CurrentGraphicsDevice.DrawPrimitives(PrimitiveType.TriangleStrip, 0, 2); //Some of the horizontal lines seems to disappear if we draw the above quad. CurrentGraphicsDevice.SetVertexBuffer(_VertexGridBuffer); CurrentGraphicsDevice.DrawPrimitives(PrimitiveType.LineList, 0, _VertexGridBuffer.VertexCount / 2); } What could be causing these lines to not be rendered? Update: I added the below code after I draw my quad and grid and it started working. But I am not sure why that works as I thought this code was to draw the WPF controls elementRenderer.Render(); spriteBatch.Begin(); spriteBatch.Draw(elementRenderer.Texture, Vector2.Zero, Color.White); spriteBatch.End();

• How to move a rectangle properly?

  - by bodycountPP

  I recently started to learn OpenGL. Right now I finished the first chapter of the "OpenGL SuperBible". There were two examples. The first had the complete code and showed how to draw a simple triangle. The second example is supposed to show how to move a rectangle using SpecialKeys. The only code provided for this example was the SpecialKeys method. I still tried to implement it but I had two problems. In the previous example I declared and instaciated vVerts in the SetupRC() method. Now as it is also used in the SpecialKeys() method, I moved the declaration and instantiation to the top of the code. Is this proper c++ practice? I copied the part where vertex positions are recalculated from the book, but I had to pick the vertices for the rectangle on my own. So now every time I press a key for the first time the rectangle's upper left vertex is moved to (-0,5:-0.5). This ok because of GLfloat blockX = vVerts[0]; //Upper left X GLfloat blockY = vVerts[7]; // Upper left Y But I also think that this is the reason why my rectangle is shifted in the beginning. After the first time a key was pressed everything works just fine. Here is my complete code I hope you can help me on those two points. GLBatch squareBatch; GLShaderManager shaderManager; //Load up a triangle GLfloat vVerts[] = {-0.5f,0.5f,0.0f, 0.5f,0.5f,0.0f, 0.5f,-0.5f,0.0f, -0.5f,-0.5f,0.0f}; //Window has changed size, or has just been created. //We need to use the window dimensions to set the viewport and the projection matrix. void ChangeSize(int w, int h) { glViewport(0,0,w,h); } //Called to draw the scene. void RenderScene(void) { //Clear the window with the current clearing color glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT|GL_STENCIL_BUFFER_BIT); GLfloat vRed[] = {1.0f,0.0f,0.0f,1.0f}; shaderManager.UseStockShader(GLT_SHADER_IDENTITY,vRed); squareBatch.Draw(); //perform the buffer swap to display the back buffer glutSwapBuffers(); } //This function does any needed initialization on the rendering context. //This is the first opportunity to do any OpenGL related Tasks. void SetupRC() { //Blue Background glClearColor(0.0f,0.0f,1.0f,1.0f); shaderManager.InitializeStockShaders(); squareBatch.Begin(GL_QUADS,4); squareBatch.CopyVertexData3f(vVerts); squareBatch.End(); } //Respond to arrow keys by moving the camera frame of reference void SpecialKeys(int key,int x,int y) { GLfloat stepSize = 0.025f; GLfloat blockSize = 0.5f; GLfloat blockX = vVerts[0]; //Upper left X GLfloat blockY = vVerts[7]; // Upper left Y if(key == GLUT_KEY_UP) { blockY += stepSize; } if(key == GLUT_KEY_DOWN){blockY -= stepSize;} if(key == GLUT_KEY_LEFT){blockX -= stepSize;} if(key == GLUT_KEY_RIGHT){blockX += stepSize;} //Recalculate vertex positions vVerts[0] = blockX; vVerts[1] = blockY - blockSize*2; vVerts[3] = blockX + blockSize * 2; vVerts[4] = blockY - blockSize *2; vVerts[6] = blockX+blockSize*2; vVerts[7] = blockY; vVerts[9] = blockX; vVerts[10] = blockY; squareBatch.CopyVertexData3f(vVerts); glutPostRedisplay(); } //Main entry point for GLUT based programs int main(int argc, char** argv) { //Sets the working directory.

• Knockback enemy based off of direction sprite is facing

  - by pengume

  Hey Everyone, Today I am trying to make it so if I hit the enemy then the enemy well be knocked backwards in the direction the sprite is facing. I am rotating the sprite around 360 degrees using a joystick on the screen and wanted to know the best practice or ways to accomplish this. I have come up with a few ideas but none of them make use of the sprites angle he is facing just a check to see if I hit the bottom then move him upward and so forth. I am just stumped on how to apply the sprites angle to the enemies x and y coordinate and move him accordingly. Has anyone tried this and have suggestions or things to look for? Thanks in advance.
