Irrlicht Engine

Alright I figured it out, I wasn't using the right sized primatives, for an int array I need to use irr::video::EIT_32BIT, or use short array and irr::video::EIT_16BIT (which is the default). Declarations: short prims[8]= {         0,1,2,3,         4,5,6,7 };   float size=10; S3DVertex verts[8]= {  ...

I changed my vertices to the S3DVertex type, but I'm having trouble with the normal vectors, mainly because I've never had to use them to draw anything standard (aka just to draw a simple shape with no translations/other transformations) in OpenGL. I figured at first the normal vector would be the &...

I've found that drawing things yourself can be faster because you can do a whole lot of them at one time. Take Minecraft for example, try drawing 200,000 box nodes vs. drawing all the faces of the cubes at once, it's amazing how much faster it is. I'm going to do something similar with foliage and s...

I'm not quite sure what I'm doing wrong, I can't get anything to show up on the screen. I looked at a few other posts and tried a few different examples but I can't get anyone else's code to show up either, am I missing something? Below is my current code (should draw a white cube face without backf...

Just curious, is there a way to use the OpenGL render function for drawing (Quads, Triangle Fans, etc...)?

It shouldn't be too expensive. I'm only combining the meshes of the different pieces when they are together. When a piece is broken off it becomes it's own mesh, then after a little bit is removed from the scene. I just need to figure out how to combine the smaller meshes in the beginning, then sepa...

Can anyone point me in the direction of some tutorials/examples of the mesh manipulator? I'm trying to come up with a system for destructible objects/terrain. My system works quite well, but I have a huge drop in FPS with all the render calls, so I need to make all the pieces of one terrain/destruct...

Why are you using a u32 for the now time? Try using an f32 and see if there is any difference, I'm pretty sure a(n?) u32 is like an int no? Because I do this: //Initialization f32 irrdt=0.0; f32 irrdtOld=0.0; //Loop irrdt=irrDevice->getTimer()->getTime()-irrdtOld; irrdtOld+=irrdt; And everything wor...

@Eigen I had no idea that developing mobile applications was this complicated (in terms of memory management). I figured there would be a "standard" to keep things in memory (delete when memory is freed, allocate when possible). Is there a mobile version of Minecraft coming out? It barely ...

@Radikalizm My game is kind of like Garry's Mod if you've ever played it, except it's more restrictive (can't create monsters or things out of thin air). It's a top-down shooter where you build ships out of small blocks and fly around in space killing other ships made out of blocks. I think a pictur...

Are you using the newest Irrlicht version? Collada is a newer feature is it not?

I figured as much (with Irrlicht not running on handhelds and such, but jirr could probably run on them through a web browser...maybe). Thing is my game is 2D and I just figured it might be cool to at one point have a handheld version, I bet it wouldn't be hard to switch it over to opengl (in fact I...

I was wondering what everyone thinks is too big when it comes to using a computer's memory? Because I'm getting up there, when I make my map pretty big my program gets bigger as well (200000k). So how big is too big? The majority of "small games" I've seen run at around 5000k-10000k. But w...

Hey I figured it out! Turns out my origin was at (5.5,5.5) on my 11x11 image, but I was using a u32 to store the origin, so it was only storing (5,5), switched to f32 and all works fine now! Funny thing is that I didn't even look at that part of the code until you mentioned the origin stuff! Thanks!...

I'm making a simple 2d game that has a grid based building system. I have several "parts" (square, triangle, etc...) And for everything to look pretty the pixels have to line up correctly. For some reason the system I am using to rotate sprites is causing some of the sprites to rotate off ...
