Moving an object at different angles...

I want to move a ball at different angles, but the farther away from 45?I get, the faster the ball moves (because the x or y value is so much larger than the other). I am adding deltaX and deltaY to my posX and posY variables. How can I make it so that the ball travels at the same speed no matter what angle it is going? Thanks.

Trigonometry. sin and cosin.

Think of velocity being represented by a length, and the possible directions for a given velocity forming a circle (working in 2D here) around the object in question, with the radius being the velocity.

Then you can use basic trig to find the x and y components of a given velocity in a given direction.

dx = Math.cos(angle)*velocity;dy = Math.sin(angle)*velocity;x += dx;y += dy;woo :)
