iDeveloperz

Yeh sure.

Create a game attribute called jump. (integer)

Then create an actor called jump switch.

Add a rule {

When touch is pressed.
Change attribute _ game.jump to 1
}

Then in your actor that you want to jump add this rule {
when game.jump = 1
(timer) __For 0.1 seconds__
Accelerate ^2500

(timer) __after 0.1 seconds__
change attribute _ game.jump to 0
}

gyroscope

Also, there's more stuff here: http://gamesalad.com/wiki/

Under heading HOW TO'S, click link "Movement", then you'll find the link: "How do I make an actor jump?"

Why mess around with attributes at all?

If you touch
Accelerate for 1.5 seconds

Turn "run to completion" off, and it'll let you jump higher depending on how long you hold down the button.

hey guys thanks alot for the help i really appreciate it but i have one more problem its kinda silly but my actor jumps but he doesnt come back down he just flies up off the screen? y is this so?

iDeveloperz

Reduce the acceleration.

Try 100 then 200....

Hipster_Owl_Studios

still nothing all it does is make my actor go up slowly but he still continues to rise up im assuming i need some type of gravity or phyics in my scene or actor idk wats the problem...

iDeveloperz

Go into the scene attributes and add gravity to about 300.

iDeveloperz

No wait in-fact don't do that. I cba telling you how to do everything else. Sorry, Im just tired thats all.

Add a rule into the actor that jumps, accelerate down 300.

Then make it collide with a floor. Then on the floor and the actors restitution 0.

Infact,

Just download this... http://gamesalad.com/game/play/54538

iDeveloperz

Add a floor actor going across the bottom of the scene where your actor walks on.

Then make you actor that jumps collide with actor of type floor.

Its all in that link I posted.
