Hi guys. I really hope you can help. Basically I want my rectangle “j_1” to remove it self from the screen when it collides with “side”. I keep getting a error. Can anyone please help me :slight_smile:

Thanks I am greatly thankful.

try this…
[lua]_W = display.contentWidth;
_H = display.contentHeight;
local physics = require(“physics”)
physics.start()
physics.setScale(5 )
physics.setGravity( -9.8, 0 )

local localGroup = display.newGroup();

side = display.newRect(0,0,20,500)
side:setFillColor(140, 140, 140)
side.x = 1
physics.addBody(side, “static”)

function newRect()

j_1 = display.newRect(0, 0, 25, 25)
j_1:setFillColor(140, 140, 140)
j_1.x = _W/1 + 50
j_1.y = _H/math.random(1.2, 8)
physics.addBody(j_1)
j_1.collision = onLocalCollision
j_1:addEventListener( “collision”, j_1 )
end

local function onLocalCollision(event )
local otherObject = event.other
otherObject:removeSelf()
end

local spawn_tmr = timer.performWithDelay( 500, newRect, 10 )
