Shoot to mouse (vectorToAngle) issue

h.rashid13

In my project, I have it set so that a projectile is spawned on mouse click and it's velocity is changed to:
vectorToAngle(mouse.posX - actor.posX, mouse.posY - actor.posY)
so that my projectiles are always fired to the mouse location.

The issue is when I move to a particular part of the scene. Suddenly, the mouse-to-actor angles start to mess up. They work fine when the actor is near the beginning of the scene, but the angles become wild as I move through the scene.

I have attached my project so that you can take a look. Frank is the main actor, Projectile is the bullet, each are constrained to Game variables. WASD to move and mouse to shoot.

@h.rashid13 -- The projectile actor is not taking the camera movement into account. This forum discussion might help:

I was talking about this issue in a thread just this morning...

make sure the value you are using to calculate your angles is an Absolute (abs) value.

Hi @h.rashid13 if you're updating an attribute with the results of your vectorToAngle, make sure this attribute is set to Angle and it'll work fine for you.

Here's a little test to show you what I mean:
