Re: Collision systems WIN

You're shitting me, the DS CPU doesn't have a floating point unit? Crazy as a snake's armpit.

Oh, and yes, this is on the Wii.

Re: Collision systems WIN

It's a 2D system. I guess it uses AABB although I had forgotten that term. It's just been "my boxes" for the past few months. :) And I guess I have representations of mass and force that I use just a little bit, so it's not purely kinematics. I'm using floats. Why did you use fixed point numbers in ...

Collision systems WIN

YESH MY MOVEMENT SYSTEM WORKS! KINEMATICS AND COLLISIONS BABY!

Sorry, it's been a long time coming, and don't have anybody else to say it to. Anybody else have any collision system experiences they'd like to share?

Re: Mixing GX and direct framebuffer writing

You can either wait for syncro and write your overlays just before copying the frameBuffer... How do you wait for synchro? Synchro with what? Do I actually want to draw my overlays before calling GX_CopyDisp? My code is as follows: GX_Begin(GX_QUADS, GX_VTXFMT0, 56); // some textured quadrilaterals...

Re: Commercial Games

Where does the name GX come from? Is it in the machine itself, or in some documentation, or something else?

Re: guPerspective crashes my Wii app! help!

The code you gave doesn't actually do anything. I ran it on my machine and it exits immediately, but it doesn't crash. And now that I look carefully at your code, you just create a WiiManager object, (calling initVideoSystem in the process) and then destroy it. I tried putting the loop from neheGX L...

Re: guPerspective crashes my Wii app! help!

guPerspective looks like this: void guPerspective(Mtx44 mt,f32 fovy,f32 aspect,f32 n,f32 f) { f32 cot,angle,tmp; angle = fovy*0.5f; angle = DegToRad(angle); cot = 1.0f/tanf(angle); mt[0][0] = cot/aspect; mt[0][1] = 0.0f; mt[0][2] = 0.0f; mt[0][3] = 0.0f; mt[1][0] = 0.0f; mt[1][1] = cot; mt[1][2] = 0...

Re: Graphics

As far as I know, GX is exactly how you operate the graphics processor. There aren't other languages or frameworks. Here's where I started: http://wiki.devkitpro.org/index.php/libogc/GX Be warned, I'm not sure that this is all correct. I found this helpful because I was a complete n00b to 3D graphic...

Mixing GX and direct framebuffer writing

I started programming the Wii by just writing pixels directly to the framebuffer. I've sinced learned how to use GX to draw textured polygons, which makes blending run much faster than it does on the CPU. Now I want to combine the two methods. I want to draw a scene using GX and then draw some "over...

Re: Textures directly from files

That helped. I got it working at last. The filename definitely needed the path prefix "sd:", and I also needed to call fatMountSimple before the texture load call, as in __io_wiisd.startup(); fatMountSimple("sd", &__io_wiisd); TPL_OpenTPLFromFile(&neheTPL, "sd:/NeHe.tpl") WinterMute, are you some so...
