How to stack blocks like this game ?

I use dynamic bodyType for the blocks but the blocks falling down when stack too high .

local physics = require "physics" physics.start() physics.setGravity(0,15) local myGroup = display.newGroup() local land = display.newRect(200,400,400,10) physics.addBody(land,"static",{ density= 3.0, friction=0.5, bounce=0 } ) myGroup:insert(land) local y = 200 local function spawn() local block = display.newRect(200,y,50,50) myGroup:insert( block) physics.addBody(block,"dynamic",{ density=3.0, friction= 0.5, bounce=0 }) y = y - 50 myGroup.y = myGroup.y +30 end timer.performWithDelay(2000,spawn,0)

 Well in the real world if you stacked blocks that uneven, the entire structure would fall like you’re seeing. I suspect the video is either a) removing the old blocks that are off screen or b ) or are being made inactive. See: https://docs.coronalabs.com/api/type/Body/isBodyActive.html

Either technique would solve the problem. Though I personally would let it collapse, take points away for blocks that fall off the structure and make them build back up… But that’s me.
