I had posted this in the Feedback thread, but it belongs here as well I think. No more double-posting for me Idea for implementing roll/evasion in ShadowGun:
Double-tap (on the side of the screen for look) triggers roll in whatever direction you're moving.Melee:
I also figure double-tapping on the left side of the screen (the side for movement) to trigger melee. This way you can still look around/get a bead on the enemy as you fillet them. Melee attacks would be picked at random from maybe 3 or 4 different executions, or perhaps based on proximity and weapon in hand.Sniper Mode:
For sniper mode, use the iOS 'pinch' gesture to zoom in--but have it only work when the sniper rifle is selected, and force it to only recognize the pinch from the extreme corners of the screen (so that it doesn't affect moving and looking).
