  • Assigning a colour to imorted obj. files that are being used as default material

    - by Salino
    I am having a problem with assigning a colour to the different meshes that I have on one object. The technique that I have used is the first approach on this site. Is it possible to export a simulation (animation) from Blender to Unity? So what I would like to do is the following. I have about 107 meshes that are different frames from my shape key animation of my blender model. What I would like to have is that the first mesh will be bright green and up to the 40th mesh the colour turns to be white /greyish... the best would be if I could assign every mesh by hand a colour, however they are all default materials. And if I assign the object a colour, the whole "animation" is going to be in that colour

  • The Back Side of Exceptions

    This article illustrates the risks of exceptions being thrown where it is generally not expected, e.g., a library function or a finally block, and shows ways to prevent some insidious errors (such as inconsistency of program data or loss of exception information).

  • Verb+Noun Parsers and Old School Visual Novels [duplicate]

    - by user38943
    This question already has an answer here: How should I parse user input in a text adventure game? 6 answers Hi I'm working on a simple old school visual novel engine in Lua. Basically I have most of the code set up besides one important feature. The Text Parser. Lets get into how words are generally structured. In the screenshot I input the command "my wish is for you to die" --How would a human understand this? my = noun/object wish = verb is = connective_equator similar to = for = connective_object (for all objects of ..) you = noun/object to = connective_action similar to do die = verb --the computer can then parse this and understand it like this (pseudo example) my = user you = get_current_label() you = "Lost Coatl" wish = user_command user_command = for all_objects of "Lost Coatl" do die() end execute user_command() What other ways do videogames use text parsers, what would be the simplest way for a newbie coder such as myself?

  • Java graphic objects as in flashgames

    - by Ryu Kajiya
    How is it possible (with the standard Java2D engine) to use small sprites like graphic objects? For those who don't know what I mean, in all those Flash-games like on Facebook they put small sprites on the screen which react to mouse-over and clicks. I tried to do the same in Java but can't find a good method. Swing components always spread over the whole bitmap, but I only want to get a reaction from the object when the mouse is over a pixel that's not transparent. So basically checking every time if the object below the mouse contains a non-transparent pixel (which i believe could be pretty intense in a gameloop or repaint loop). I have no idea how to implement such a thing efficiently.

  • How do I convert a partially transparent image into polygons?

    - by user82779
    I'm using GLEE2D, a level editor allowing me to import images, scale them, rotate them, and position them onto layers and export the data into XML format. However, it does not tell me objects' boundaries. I can calculate them, but only given the original image's polygons. How do I get polygons of objects in a transparent image? An example object (I outlined it): How would I turn the object, knowing the scaled size of the image, into polygons? Is there an algorithm for this? I'll use OpenGL to draw them.

  • What's a good way to store a series of interconnected pipe and tank objects?

    - by mars
    I am working on a puzzle game with a 6 by 6 grid of storage tanks that are connected to up to 4 tanks adjacent to them via pipes. The gameplay is concerned with combining what's in a tank with an adjacent tank via the pipe than interconnects them. Right now I store the tanks in a 6x6 array, vertical pipes in a 5x6 array, and horizontal pipes in a 6x5 array. Each tank has a reference to the object that contains both tanks and pipes and when a pipe needs to be animated filling with liquid, the selected tank just calls a method on the container object telling it to animate the pipes it is connected to (subtract 1 from row or column to find connected pipes). This feels like the wrong way of doing it, as I've also considered just giving each tank references to the pipes connected to it to access directly.

  • Retrieve the coordinates of the *occluding* (closest/drawn) pixels during 3D overlap, using OpenGL?

    - by Big Rich
    Hi, Sorry if the question is not worded well, I'm a new to both 3D and OpenGL. How could I go about obtaining the 3D coordinates of the occluding object, at the point where occlusion is happening (i.e. the 'intersection' of the object in front/closest to the screen)? Just to offer a [very] rudimentary, visual, example, if you were to form an index-finger cross, with your right hand closest to your face, I'd like to know the coordinates of the part of your right finger which obscures the other finger (obviously back within the OpenGL context - no jokers ;-) ). If there is a way to find out both about the occluder (hider) and the occluded (hidden) objects in OpenGL, then that would be of great use, also. Cheers Rich

  • dun goofed the files in /usr/lib/x86_64-linux-gnu/

    - by tipu
    there was some weird package issue with (in my limited understanding) 32/64 bit libraries, so i went around making symlinks to the file my lamp installation expected to the ones that actually existed. i did this for a # of files in here: /usr/lib/x86_64-linux-gnu/ however php still ended up not working (separate issue) and now i believe i have a screwed up lib directory. is there a way to revert those library files?

  • How do I duplicate a Box2d simulation, mid-simulation?

    - by Whyte
    I want to serialize the state mid-game, send it over the network to an identical computer (same CPU, same OS, same binary), load it there, and have the two games run in tandem doing the exact same simulation, without one of them drifting off and going haywire. In short: I want pop-in, pop-out networking support on my HIGHLY physics-intensive game, where sending object coordinates every few seconds is impossible, due to having thousands of objects, and many clients. I tried this with Box2D, and saving an object's location/velocity/etc wasn't enough... there's internal state that's not accessible through any public methods. My current workaround is to force EVERY client to save its entire worldstate and reload it from scratch, whenever a new player connects... but this is obviously bad practice, because it hangs the game for everyone whenever someone new connects. However, it works, with zero desynchronization. So, anyone know of any other techniques that can help me? Or should I just kiss my project goodbye?

  • What Design Pattern is separating transform converters

    - by RevMoon
    For converting a Java object model into XML I am using the following design: For different types of objects (e.g. primitive types, collections, null, etc.) I define each its own converter, which acts appropriate with respect to the given type. This way it can easily extended without adding code to a huge if-else-then construct. The converters are chosen by a method which tests whether the object is convertable at all and by using a priority ordering. The priority ordering is important so let's say a List is not converted by the POJO converter, even though it is convertable as such it would be more appropriate to use the collection converter. What design pattern is that? I can only think of a similarity to the command pattern.

  • How to create a large level game?

    - by Siddharth
    I want to know how to create a large game which has more than one level in it and those levels are loaded from the xml file. In my game I have many objects for each different level which I have to load when use click on it. At present for example my game contain 20 levels and now I was loading all the graphic object for all 20 levels. But the correct way was that only load graphic of that particular level only. So I don't know how to do that. So please explain this by providing game example. At present I was creating a class for each my game object image by extending sprite to it. I know it was not a suitable way so provide guidance on it. Basically I want to know how to create large games in andengine? Please help me about that because it will provide help to other community member also because andengine did not have proper documentation for learning developer about how to manage large game?

  • Can a domain specific language be used to representing the Open SRD

    - by NeoModulus
    I am in the early stages of creating an open source C# library that would allow developers to drop in the open SRD (http://www.d20srd.org/) into an existing project. Abstracted it is a complex set of tightly coupled business rules. Having previously worked on an adaptive object model project for health care risk management I began with that pattern in mind. Due to the high coupling of rules it is becoming apparent that the project may require some kind of scripting. Have started researching DSL implementation I am now considering scraping the adaptive object model for a domain specific language. I have not work with domain specific languages so my question is it reasonable to assume a domain specific language can be used to representing the open SRD?

  • khotkey: starts firefox on any key?

    - by Adobe
    I have many scripts which I call with khotkey. However -- in my other laptop -- khotkey wouldn't call the script -- but tries to open the command in firefox. I checked -- the scripts are executable, and are mine. What else could that be? When I start the command from konsole -- it works as expected, but when I call it with khotkey -- it doesn't. I guess someone shadows my keybiding. But who could that be?

  • Physics for moving blocks

    - by Gabson
    I'm working on a 2D game for windows phone where the player moves blocks around to bounce a laser beams. I need to create some simple physics for moving the blocks. For the moment I have a simple collision class, telling me if two rectangles collide. But that's not enough because when I'm moving a block the rectangle/rectangle function doesn't work. By Doesn't work i mean,I manage the collision but I don't how to stop the block mooving while the user sliding the block. The collision response for the block I want is if the user tries to slide it on another object, the block should slide up against the other object and not overlap. How would I go about implementing this functionality?

  • Is there a prohibition against scaling collision shapes at runtime?

    - by Almo
    So, I have a StaticMeshComponent attached to an Actor: Begin Object Class=StaticMeshComponent Name=StaticMeshComponentObject StaticMesh=StaticMesh'QF_Art_Powers.Mesh.GP_ForcePush' CollideActors=true BlockActors=false //Scale3D=(X=5, Y=1.5, Z=3) // ALMODEBUG End Object CollisionComponent=StaticMeshComponentObject Components.Add(StaticMeshComponentObject) Ordinarily, the actor gets spawned, anything touching it gets bumped, and the actor despawns itself. If I set the Scale3D as a default property, everything works as I expect. But I want to scale it at runtime, like this: function SetImpulseComponentTemplate(QuadForceBoxImpulseComponent Value) { Local Vector ScaleVec; ScaleVec.X = Value.Length; ScaleVec.Y = Value.Width; ScaleVec.Z = Value.Height; CollisionComponent.SetScale3D(ScaleVec); } When I do this, the thing only collides as if it were not scaled. If I leave the actor spawned so I can see it, it is scaled. If I also "show collision", the collision displays correctly as well. Is there a prohibition against scaling collision shapes at runtime?

  • Keeping application backend and UI synchronised

    - by Deanna
    Hi all. I have an app that works with a list of objects so has one central keyed list. The main window has a tree containing these object with some information, which is easy enough to populate as a one off event after loading. Now, the complicated part, any part of the application can add, remove, and more importantly change the details of those objects at any time (all in the same process) and I'd like the tree to update to suit. I have a few options including passing events back down from the object to the list to the form which seems to be the most flexible way. I can also do it lazily and repopulate the tree each time or periodically (very hackish). Does anyone have any better thoughts on how to structure this? This is being done in C# 2.0 but the concepts apply to any environment. Thanks

  • How to learn programming from very basic level to advanced level? [closed]

    - by user1022209
    I know many programming languages ,skills and concepts in very basic, such as PHP, Java, Object-oriented technology. Using PHP, I can build a simple website with CRUD, login function. Using Java, I can make an basic swing csv/plain text editor in which user can switch between 2 different views. In term of object-oriented Technology, I clearly understand what encapsulation, inheritance and Polymorphism are I want to know more about programming. Sometimes I "google" some of the topics I am interested at , the more I see on the internet, the more I feel I am a small potato in the world ( indeed I am ). The codings/concepts are difficult to understand. I lacks confidence right now so I am asking this question :( What is the best way to learn programming to advanced level? Just buy a book and read it page to page? Thanks for any helps
