Why is Bullet angle wrong?

I have a top-down game. 384/128 is a position directly above (North) of the Worker sprite. But when I click the Worker it moves to the right (East). The angle calcs to -90, why not 0? Why is the angle calculation not working?...

-90 is correct, since -90 is up. The issue is when the bullet behavior has a speed of zero, then setting the angle of motion has no effect, it will always become 0 (right). The solution is to set the speed first, then the angle of motion.

The reason behind this is the bullet behavior stores velocity in two variables: vx and vy, the first being for horizontal velocity and the other for vertical. When the speed is zero then:

vx=0

vy=0

The angle of motion is set by first calculating the current speed with the Pythagorean theorem: speed=sqrt(vx^2+vy^2)

next the new velocity is set in the angle you want:

vx = speed*cos(angle)

vy = speed*sin(angle)

But since the speed is zero vx and vy will become zero.

R0J0hound That was it. Thanks for the extra detail. It actually makes sense when you see that. Thank you!!!!
