on debugger there's a "trevelled" under Bullet tab - it just shows distance the sprite travell from bullet activation.
and what i was doing is that:
When you press mouse button, bullet activates and move sprite to mouse position, sets distance value between mouse and sprite as a bullet "range".
If "bullet exceeded range" then bullet is deactivated and stops the sprite.
ie. on first couse click "range" is 300 (distance between mouse and sprite)
when sprite moves, "travelled" option is rising, when it reach "range" witch is 300 - > sprite stops - everything is fine.
but when you click mouse one more time the "travelled" keep rising up from 300...
It's nothing serious really, just having fun testing and playing with behaviors.
