Moving static bodies with touch event possible?

Physics
#1

Hey guys!

I try to move a static body with touch event on x-axis. On top of the static body (rect) lying several dynamic bodies (circles). When the static body moves away the circles dont fall to the ground but “stay in the air”. Where is the mistake?

Thanks in advance!

Need code :slight_smile:

You have to set the .isSleepingAllowed property for the circles.
Dynamic bodies are send to sleep after a while of rest, so they take less memory. But that can be really annoying on the other hand.

myCircle.isSleepingAllowed = false

Here is my code. But isSleepingAllowed flag is the thing I needed. Thank you very much guys!

local physics = require("physics"); physics.start(); physics.setGravity(0, 9.81); physics.setDrawMode("hybrid"); local \_DCW05 = display.contentWidth/2; local circle = display.newCircle( \_DCW05, 10, 50 ); physics.addBody(circle, {radius = 50}); circle.isSleepingAllowed = false; local groundShape = {-50,-50, 50,-50, 50,50, -50,50}; local ground = display.newRect( \_DCW05, 300, 100, 100 ); ground:setReferencePoint(display.CenterReferencePoint); ground.x = \_DCW05; physics.addBody(ground, "static", {shape = groundShape}); function ground:touch( event ) if event.phase == "began" then self.markX = self.x elseif event.phase == "moved" then local x = (event.x - event.xStart) + self.markX self.x = x; end return true end ground:addEventListener("touch", ground);
