If the image point system doesn't work (don't know why though), I would simply go with some expressions.
If the Sprite is a simple bar, you can use the Bar coordinates and a percentage of its length to simulate an image point.
Let me give you some examples:
- Image point at 2/3 of the bar's length:
X coordinate: Bar.X + Bar.Width * (2/3)
- Image point at 55% of the bar's length:
X coordinate: Bar.X + Bar.Width * 0.55
(Assuming, the Sprite's hotspot is on its left.
If it's in the middle, use
Bar.X - Bar.Length/2 + Bar.Length * 0.55
for the second example)
Obviously use the Bar's Y coordinate for the Y coordinate of the simulated Image Point.
Hope this makes sense to you.
