well I am working on collision detection between two boxes, the paddle and the ball are both squares involved in a breakout game, here is the code I have come up with, I just want to know if this is proper code for collision detection if((x+5.0f>-20.0f+i)&&(y+5.0f>-90.0f)&&(x<-20.0f+i+40.0f)&&(-90.0f<-90.0f+10.0f)) I am not sure where to put the parenthesis, please let me know if you need more information

That almost looks like the basic bounding box collision, but with one important difference that need to be changed. Your code will only work if the ball is completely inside the box, because all four conditions have to be met. Touching the box at any side should be the minimum. Replace each "&&" with an "||" so that only one side of the box will need to be checked at a time.

Furthermore, as you continue working on the game, you should probably make the ball bounce back at different angles every time, depending on what part of the paddle it hits.

-90.0f<-90.0f+10.0f you can take this out because its always true. Also note if you change && to || this part will always make your if statement true.

You might want to consider putting the code from your other post into a function, instead of hard coding it like you have it.
