Well the idea here is to add effects to weapons that don't count in the hitbox. There are two ways this can be done:
- Manually assign a hitbox size
This one is simple, and I prefer this one over the other. All you do is just assign a hitbox size in one of the data files. you assign the x,y size and the x,y coords of your actual image that the TOP LEFT corner of the hitbox will start at. This is useful if you have something like a flame overcoming your bullet and leaving a trail, so you want the middle front to be a hitbox. - Allow usage of separate files which will be the effects
This one is a little bit more complicated. Basically, when making your weapon bmp/png, you can also assign a file to act as an effect with the bullet, that don't count as part of the hitbox. An example is when you make a weapon that has a huge glow. The problem now is that your 100x100 bullet image now has a HUGE hitbox. In this way, you could crop the image down to what you want your hitbox to be, and export the other stuff to a different image.
I hope I explained well enough, but if you have any questions, feel free to ask.
