This should be in the beginners forum I think
Basically, you need to keep an array of all your active bullets (adding and deleting as nessecary).
You iterate through that array, and compare each bullet's bounding box with the player bounding box. If one overlaps, then a bullet has hit the player.

Easy. Read the help, that's what I did.
Here's a snippit from my code, where I do bounding box collision between the "sydney" model, and the "faerie" model;
Code: Select all
if (sydney->getTransformedBoundingBox().intersectsWithBox(faerie->getTransformedBoundingBox())){
printf("collision\n");
}
Something that tripped me up at first is; you can't used getBoundingBox, because it only returns the size and position the bounding box was when the model was loaded. You need to use getTransformedBoundingBox, to get the one that actually represents where they really are and their current size.
