Detect when a button is released?
How do you detect when a button has been released?
For example, pressing R2 does a pull back punch anim and then releasing R2 does the punch attack anim. If you were to hold it down it would hold the pull back anim until you release R2.
You can use a Signal Manipulator set to Custom Remapper, then in the Edge Mode section, set it to Pulse at OFF. This will send a pulse when the signal that was produced turned off, which is what happens when releasing a button.
