Spriting 101:

-Draw your sprite. Make sure that it fits into a power of 2-size box (64x64, 128x128, 256x256, etc.)
-If you want your sprite to be self-illuminated (energy, fire, sparks, etc.), give your image a black background.
-If you don't (debris, smoke, etc.), give your image a white background.
-If you want a combination of the two (like my Dark Energy stuff), give your image a transparent background.
-Surround your sprite with a box colored pure blue (0,0,255). Halo interprets this as the image boundary when rendering sprites, so that you can have multiple frames of an animated sprite or multiple variants of a sprite in the same image.
-Save your sprite as a .TIFF. Must be a .TIFF. Place it in a folder inside the Halo CE\data folder. (Such as Halo CE\data\bitmaps.)
-tool bitmaps . The folder with your sprite, not the file itself. Folllowing the above recommendation, you'd stick "tool bitmaps bitmaps\" into the command prompt.
-You will get errors. This is fine. Open up Guerilla and open your new sprite (should be in the same folder you told tool to compile, except now in the Halo CE\tags directory.) Change the type to "sprites," format to "32-bit color," sprite budget size to the next largest power of two after your actual image size, and sprite budget count to however many sprites you have in the image (probably one.) If you gave your image a white background, set the sprite usage (near the bottom) to "multiply/min."
-Compile through tool again. You shouldn't get any errors now.

And use the image in the particle effect. Let me know if something's still wrong.
