How would i go about writing a script that will allocate a function to the two finger touch? We are currently using one finger touch functions for the main character of our game but need to assign a two finger gesture (tap) to the secondary character.
Does unity even offer an option for two finger gestures other than the pinch?
From what I understand unity does handle touch gestures. You can look into the Input.touchCount to determine how many touches you have the loop through your touches to find out what changed. From this information you can define what a pinch is or any other gesture. There is a gesture plugin in the asset store that might make that process easier but I have never used it.
Hope that helps
