use touch properties to depict left, right, up and down movements of a character?

asma.sikandar1@gmail.com

In touch properties, there only exists four behaviours of release... n others...how do we program left, right , up and down??

it is very easy to do it if a key is pressed but how to use since iPad and other devices will only have touch and no keys...??

You want to create 4 Actors and 4 Boolean Attributes. Name Each Left, Right, Up and Down.

Inside the actor do
-------------------------------------------------
Left & Right

When touch is pressed Change Attribute (Game.Left) to true
When touch is released Change Attribute (Game.Left) to false

Inside your character do when (Game.Left) is true, constrain attribute (Self.Motion.LinearVelocity.x to Self.Motion.LinearVelocity.x-200 (Or Pick a Number)


When touch is pressed Change Attribute (Game.Right) to true
When touch is released Change Attribute (Game.Right) to false

Inside your character do when (Game.Right) is true, constrain attribute (Self.Motion.LinearVelocity.x to Self.Motion.LinearVelocity.x+200 (Or Pick a Number)

---------------------------------------------------
Up & Down

When touch is pressed Change Attribute (Game.Up) to true
When touch is released Change Attribute (Game.Up) to false

Inside your character do when (Game.Up) is true, constrain attribute (Self.Motion.LinearVelocity.y to Self.Motion.LinearVelocity.y+200 (Or Pick a Number)


When touch is pressed Change Attribute (Game.Down) to true
When touch is released Change Attribute (Game.Down) to false

Inside your character do when (Game.Down) is true, constrain attribute (Self.Motion.LinearVelocity.y to Self.Motion.LinearVelocity.y-200 (Or Pick a Number)

Download the GS controller template it has a series of on screen controllers should be in the opening window.
