collision sprite

I am made a lot of progress in my game but I have hit a small snag. in my code I am using an AABB collision detection. I have also used exit(0) to debug my code.it tells me where in my code where it is getting access to. I have put exit(0) in the AABB collision detection and it accesses it just fine. but when I put only drawcollision_one function in the AABB collision routine it does not draw my collision sprite animation. when I put drawcollision_one in the display function it works just fine. when the planes collide nothing happens but the exit(0) is accessed when the planes collide. here is the code I am working on. 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(0.5f, -0.5f, 0.0f); glTexCoord3f(0.167f + screen, 0.0f, 0.0f); glVertex3f(0.5f, 0.5f, 0.0f); glTexCoord3f(0.167f + screen, 1.0f, 0.0f); glVertex3f(-0.5f, 0.5f, 0.0f); glTexCoord3f(0.0f + screen, 1.0f, 0.0f); glVertex3f(-0.5f, -0.5f, 0.0f); glEnd(); glDisable(GL_TEXTURE_2D); } void timer(int val) { screen += 0.1667f; if (screen >= 1.0f) { screen = 1.0f; } glutPostRedisplay(); glutTimerFunc(500, timer, 0); } void coll_plane_one() { //draw bullet float x = -5.0f + horizontal; float y = 0.0f + vertical; float oWidth = 1.0f; float oHeight = 1.0f; //draw plane float xTwo = 5.0f + horizontal_one; float yTwo = 0.0f + vertical_one; float oTwoWidth = 1.0f; float oTwoHeight = 1.0f; if (checkCollide(x, y, oWidth, oHeight, xTwo, yTwo, oTwoWidth, oTwoHeight) == 1) { drawcollision_one(); } }

Even though these forums are quite friendly we all eventually grow tired of beating a dead horse.

phil's been putting this particular dead horse out there to get beaten for 14 years now, so apparently we don't grow tired of it. That poor horse just keeps getting beaten unrecognizable. For anyone who may be new to this guy's schtick, just go ahead and check his posting history. Then be aware that for some reason a lot of that posting history is no longer there. There've been a few forum migrations since the horse was first killed. I was unable to access anything from before 2012 (page 39 in his profile history) directly from his profile. Google can help ya, though! For instance, a quick search turns up hex grids from 2005, where he opens with his usual statement-as-a-question, expecting people to do the all the work, and follows it up with a blatant failure to listen. It's a pattern you might find eerily familiar.

A bit of advice to people currently in this loop of madness, and to those who might be tempted to dive right in thinking that they just happen to have the magic that'll make phil listen and learn: It's a waste of time. If this comment of his from 2013 is to be believed, he has a BS in computer science, so if 4 years of university and a subsequent decade of posting on gd.net have failed to teach him anything, then I highly doubt anyone can. You would probably have better outcome by finding an ACTUAL dead horse to beat.

I would just like to nominate @JTippetts for post of the year. I know you're a moderator but it's still impressive. I'm curious, it seems like an elaborate troll. I knew he went way back and I always read his initial post because I find it hilarious that people still reply to him over and over again like @Rutin has, but didn't realize he went THAT far back. That is perseverance trolling to say the least. There has to be anti-trolling rules on the forums, if not time to consider them haha.

Sadly I'm a sucker for wanting to help people even though I made a pretty good conclusion this will never go anywhere no matter what I type... Even my wife was telling me why I even bother and to not waste my time. Either way, that's on me for doing so. After looking through those links I'm lost for words.

At least if someone else has a similar issue, maybe some of my posts might help them, who knows....

Going forward I wont be engaging.
