Jumping and falling to other object

Hi!

i Create some jumping

local ground 400; local jumpHeight = 150; local RunnerDown = function( obj )     runnerTransition = transition.to( obj, { y=self.y + jumpHeight, time=runnerTrasistionTime} );     runnerRotation = transition.to( obj, { rotation=obj.rotation  + 90, time=runnerTrasistionTime } ) end function RunnerJump(self, event)         runnerTransition = transition.to( self, { y=self.y - jumpHeight, time=runnerTrasistionTime} );         runnerRotation = transition.to( self, { rotation=self.rotation  + 90, time=runnerTrasistionTime, onComplete=RunnerDown } ) end local runner = display.newRect( 0, ground, 100, 100 ); runner:setFillColor( 1, 0, 0 ); runner.myName = "runner"; physics.addBody(runner, { bounce = 0.2 }); runner.touch = RunnerJump;

but my object allways go to my start point, i want runner stay on some kind of floor. Any solutions or hints?

If you want to use physics then don’t use transitions to move it butobject:applyForce().

You need a floor which has a physics body as well so you don’t fall off the screen.

Then if you want to jump on ledge that ledge has to have a physics body also not just the runner.

Check the physics API docs for more.

:slight_smile: i try apply force many time, but i want some animation, i will try preCollision :slight_smile:

You can use transitions for animation (like the rotation you are doing in code) but don’t use transitions to move the runner.
