Strange Bug in my Program

[John Dupe]

I'm trying to re create Pong in the Vita with HenKaku, but when the ball hits the top of the screen (only the top, I've checked) it freezes and the Vita spits out a core dump. Is there anything I should be looking out for?

My code checks if the ball hit the top of the screen, and if so, negates the speed of the ball (sending it the other way)

Am I doing something wrong?

Do you mind posting the code for your collision of the top of the screen? A number of popular issues come to mind when hearing this.

Code: Select all

		
if((ball.y + ball.radius) > SCREEN_H)
{
	ball.y = (SCREEN_H - ball.radius);
	ySpeed = -ySpeed;
}

ball is an object of a typdef struct called circle.
ySpeed is a uint32_t set to either 5 or -5.

You should definitely be using a signed int for negative numbers.

***. I knew it was something simple, sometimes you just need a fresh pair of eyes to check over your code, eh?

Nevermind. ySpeed is now defined as a signed int, but the problem persists.
