The tutorial shows a ball game where a camera follows the ball always at a certain distance from the target ball. I get that.
How might I go about following the target ball from a fixed location? Like camera is locked down and target follows the ball?
Looking for hints.
thank you.

VECTOR temp;
vec_set(temp,ball.x);
vec_sub(temp,camera.x);
vec_to_angle(camera.pan,temp);

if camera looks backwards try this one:

VECTOR temp;
vec_set(temp,camera.x);
vec_sub(temp,ball.x);
vec_to_angle(camera.pan,temp);
