Strange movement behavior

Questions & Answers
1

I just created a small projectile for my game and added a little script to control its movement. It is a really easy script, but it behaves incorrectly.

var projSpeed : int = 1;

function FixedUpdate() {
	if(statics.turnActive) {
		transform.Translate(transform.right * projSpeed);
	}
}

(turnActive is set in another script, based on player input)

Now it does move the projectile, but when I rotate the projectile model 90° in the scene view, the movement direction turns 180°. I have no idea why it should do that. I can change the direction 90° by using transform.forward instead of transform.right, obviously, but that doesn’t solve the problem. While some enemies will fire in the correct direction, others will fire up to 90° to the left/right, or even backwards.

Ok…I am stupid…got it now.

transform.forward creates a vector in world coordinates, so using that in a local reference system applies the rotation twice.

Simple solution: Either use Vector3.forward, or Space.World as reference system.
