Thread: Reference to making breakout game

Hi darkness, thank you for ur elaborated explanation. I really think your suggestion is good.

Code:

// will be using a shrunken rect to represent round ball
Ball 
-shrunkenX:double  // coord of top left corner of shrunken rect
-shrunkenY:double // in pixel
-x: double // coord of ball
-y:double 
-x_vector:double // vector of ball movement
-y_vector:double

This time i will keep two double attribute x_vector and y_vector instead of angle. Each time i need to update the position of the ball. I simply do a

Code:

x +=x_vector;
y +=y_vector;

i can also change the magnitude of the vector to determine the speed of the ball.

Reflection is a matter of change the sign of x_vector and y_vector as you mentioned.

Now i can start coding the actual game. Once again, thanks!

Yeah not a problem. Best of luck to you.
