Look at that 2D sample. There you can see how to animate pictures.
In simple, you have to change the image which has to be drawn.
1. picture 1
2. 0.5 seconds later picture 2
3. 0.5 seconds later picture 3
4. 0.5 seconds later picture 4
1. picture 1
2. 0.5 seconds later picture 2
3. 0.5 seconds later picture 3
4. 0.5 seconds later picture 4
and so on.

Code: Select all
ITexture* spriteImage = driver->getTexture("test.bmp");
driver->makeColorKeyTexture(spriteImage,SColor(0,255,0,255));
IBillboardSceneNode* spriteObject = smgr->addBillboardSceneNode(NULL,dimension2d<float>(50,50),
vector3df(0,0,0));
spriteObject->setMaterialTexture(0,spriteImage);
spriteObject->setMaterialFlag(EMF_LIGHTING,false);
I got problem with this. The billboard appeared but it didn't have any texture on it! The whole thing white in colour.

I've tried the animator class found in this forum as well. but what I got was a flickering white rectangle.

A better way would be to resize your image. Crop it to be a multiple of 2^X. It will then display correctly in Dx8, openGL etc.
multiples of 2^X are sizes like:
16
32
64
128
512
1024
2048
and so on. You can mix them to, like 64x512. I changed my game to use these sizes and it ran perfectly on all drivers

the image is already 128x128 because I am already clear about this 2^n thingy. The pic didn't show at all!

I guess it doesn't find your KeyColor. Try to use the positional version and use (0,0), otherwise use the correct alpha value (presumably 255).
Next thing, you will probably want to use an alpha channel transparency with your modified texture, so set the proper material value.
And finally, calling makeColorKeyTexture requires a mipmap regeneration of the texture, so call that one before drawing the texture.

Maybe it did not load the texture at all?
