I'm trying to implement a system whereby a "shield flare" will be shown whenever a projectile impacts the shield. The shield itself is one like in Star Wars, where it's more like a skin around the spaceship, rather than a simple bubble.
The problem I'm having is determining how to draw a simple flare effect where the projectile impacted the shield. I can determine the Vector2 point where the shield was hit. Right now, I'm able to show the whole shield whenever it's hit just fine.
The problem as I see it, is that I somehow need to mask out the shield, except for a few pixels around the point of impact. Either that, or I'm going about this the completely wrong way.
What I can do so far is draw the whole shield:
What I need is to be able to draw a piece of the shield on the point of impact:
Any help would be appreciated.
