sprite collision

all I want to do is draw a animated sprite when a bullet hits a sprite. here is my collision detection function and my sprite drawing function all I need is a second pair of eyes to look at my code. void drawcollision_one() { glEnable(GL_TEXTURE_2D); glBindTexture(GL_TEXTURE_2D, texture[3]); glBegin(GL_POLYGON); glTexCoord3f(0.0f + screen, 0.0f, 0.0f); glVertex3f(10.0f, -10.0f, 0.0f); glTexCoord3f(0.167f + screen, 0.0f, 0.0f); glVertex3f(10.0f, 10.0f, 0.0f); glTexCoord3f(0.167f + screen, 1.0f, 0.0f); glVertex3f(-10.0f, 10.0f, 0.0f); glTexCoord3f(0.0f + screen, 1.0f, 0.0f); glVertex3f(-10.0f, -10.0f, 0.0f); glEnd(); glDisable(GL_TEXTURE_2D); } void coll_plane_one() { //draw bullet float x = -2.5f + move_plane; float y = -75.0f + up; float oWidth = 5.0f; float oHeight = 5.0f; //draw plane float xTwo = -10.0f + move_plane; float yTwo = 100.0f + down; float oTwoWidth = 20.0f; float oTwoHeight = 20.0f; if (checkCollide(x, y, oWidth, oHeight, xTwo, yTwo, oTwoWidth, oTwoHeight) == 1) { drawcollision_one(); } }

What else does your game need?

to draw a collision animated sprite

These sprites are called "particles". I will begin to study how to make it in modern OpenGL using shaders, but I will not be able to help you because I do not study legacy/deprecated OpenGL 1.1. I think it is too early for you to make particles. Try to make your game without particles. Make them later.

well I am kind of lean on creativity, I don't know what my game needs next.

..trying a re-wording. what do other games have that your game does not? (menu, scoring, pause, replay, sound, enemy AI, state manager/listener, some refactoring (remove duplicating the quad draw code...?)
