How do I spawn an object at the edge of my object?

I have a turret that on shoot should spawn cones, that shoot at the enemies. By default, when creating a new object at it's place, it is being created at the center of the turret.

As you can see, this looks really dumb:

I would want something like that:

Therefore I need to shift the position of the cone to the edge of the "front" edge of the turret. (The edge it turns to the enemy.) I tried to do so with some Maths, but I failed badly (geometry isn't my strength after all). Is there a possibility to tell Construct to not spawn it in center, but rather at the edge of the other object?

Create a new image point in the turret sprite. And spawn bullets at this image point.

Like dop2000 said, click on the sprite and open the image editor and add a new imagepoint to the sprite, hold shift and click where you want it to be(holding shift will add a image point to all frames in the animation)

After that you just PIN or CREATE the object on that imagepoint that you created.
