Well after all my questions and newbie-ness, I have finally created bullets! And they actually fly at the crosshair! But now I seem to be having trouble getting them to actually collide.

I am setting the collision on for both the level's objects and the bullets upon creation, and then twice in the loop I check for collision (before new bullets can be made and afterwards). I attached my gun and bullet control code. For those looking through my code, objects 27 through 85 are the level's shootable objects.

Also, you'll noticed I have commented out the gun's animation. DBPro won't load the gun and I was wondering if there is a problem with Milkshape 3D 1.6.4's .x exporter? If there is, are there any free or trial (but non-limited) programs that can export and import .x?

ok the best way ive seen is to move the bullet with a for/next loop as soon as the gun is fired - check for collisions after each move. just make sure you dont sync until uve finished the loop. this will give 'instant bullets' which are generally fast and reliable. hope this is of some help!

I suggest you look into the "intersect object" command. It's made for things like this.

This may help you. The code's for DBC, but the principle is the same. Scroll down to my post with the pseudocode, it deals with making sure bullets or any other fast moving objects actually register collisions properly.
