This action checks for the initial down press on a gamepad button for a given gamepad index. It will return true on the single game tick that the gamepad button is pressed down and false at all other times. If you enable the not modifier, this action will be reversed, and check if the button has not been pressed down, returning false on the game tick that it has been pressed down and true at all other times.
Note that to add actions into the "if" block, they should be dropped to the side of the action, as shown in the image below:
These actions will now be run if the "if" evaluates to true, while any actions dropped elsewhere will be performed after the "if" block.
Argument Description Gamepad The gamepad index. Button The name of the button to check. Not Negate the check (true becomes false and vice versa)
The above action block code polls the button state of gamepad 0 every step and if a button is being held down it checks for the initial button down press. If the check is true on the initial down press, a sound is played, then, while the button is held down, the sprite blending is changed to red. If the button is not being held down, a check is done on the button release to reset the blending colour to white.
