collision help
November 19, 2004 06:34 PM
I need to detect colision of a ball and a paddle for a game of pong, I have tried sooo much and it wont work, here are the dementons:
paddle: 50,170
ball: 52,52
xpos,ypos: the x and y position of the paddle
bxpos,bypos: the x and y of the ball
|
|^
|y
|
|
|
| x->
--------------------
everything I do bounces off the very top and above the paddle, or it doesnt care if the paddle is there, it will bounce, anyonw know that the if statment should be?

Hows about you post the code you're using so far?

if (bxpos>750 && bypos <= (ypos + 171) && bypos <=ypos)

if(bypos < ypos + 50 && bypos + 170 > ypos) // collision!!1Try that. [smile]

Well it bloody should. Are you checking the xposition too? Maybe we need to see more code.
EDIT: Corrected a stupid typo in my earlier code post. If you copied and pasted without reading it, shame on you and try again. [wink]

here is relevant code
void pong::hit(){ if(bypos < ypos + 50 && bypos + 170 > ypos) { bspeed = -bspeed; buspeed = -buspeed; }}//init stuff xpos=800; ypos=150; bxpos = 250; bypos = 300; bspeed = 6; buspeed = 0;

How are you using it? I don't see a check for the x position. Dunno what the speeds are for either (I can assume one of them is the ball's x velocity).

there is bspeed ans buspeed, at before it draws it goes:
bxpos +=bspeed;
bypos +=buspeed;
speed is always 6 and uspeed is 4-7, bspeed is the x speed, buspeed is the y's
bxpos +=bspeed;
bypos +=buspeed;
speed is always 6 and uspeed is 4-7, bspeed is the x speed, buspeed is the y's

Oh, crap. I mixed up your variable names; I thought b*pox was for the block/paddle.
That might work better.
if(ypos < bypos + 50 && ypos + 170 > bypos) // collision!!1That might work better.
