So I was working on adding a simple "floor" (basically code that keeps the camera from going below a certain level) and jumping when I encountered a bug that made my camera slowly look down, even though my code didn't have anything to do with camera.target. Some times will dip down to a y value of maybe 1.999... if anyone has a better solution than setting a depth limit, please let me know. Here is the code that deals with preventing the camera from falling, and jumping. if anyone needs all of the code, I will be happy to provide it.
if (IsKeyDown(KEY_SPACE)) {
if (camera.position.y <= 2.0f) {
yMomentum = yMomentum + speed;
}
}
// forces camera to be above 0
if (camera.position.y < 2.0f) {
camera.position.y = 2.0f;
yMomentum = 0;
}
edit. here is all the code if needed:
