How to make actor jump when touching the screen

Mayhem_Madness

Hello everyone, Thor speaking here. I am a bit stuck on this, i have seen a couple tutorials but most of them are with arrow keys not with touching the screen.
So i wanted to know how to make an actor jump up when touching the screen.
Also when it is in mid-air, how would i make it do another jump, but i only want it to be able to do 2 jumps in total, then it will fall back down..

Thanks.

Thor.

Let me make you a quick demo.

Here you go. Simple once you know how to do it. Hope it helps.

There are a few ways you could detect a touch to the screen.

1. Access the Attribute game.Touch.Count from the Attribute Browser, Devices » Touches » Count.
2. When that equals 1 trigger your jump routine

You could also place a large invisible 'button' graphic over the entire screen and use a 'when touch is pressed' rule applied to the button actor to trigger the jump routine.

Below is a link to a tutorial that covers setting up a double jump action, along with other movement options. The tutorial uses keyboard input, so you'd need to adapt it to whichever method you choose to trigger the actual jump.

Thankyou Braydon, your a star.

But, do you know what i would need to change, so it jumps when it touches the screen not the actor itself?
Sorry for the inconvenience.

Thankyou.

Thor.

It does exactly that. When a touch is detected anywhere (mouse is down), it jumps. You do not need to tap the actor to make him jump.
