collision doesn't happen when object are moving fast

I think other may have faced the same problems. I try the tip at http://blog.anscamobile.com/2011/08/solutions-to-common-physics-challenges/ but it doesn’t work for me either. Below is the code

local physics = require "physics"  
physics.start()  
physics.setVelocityIterations( 6 )  
physics.setPositionIterations( 16 )  
local obj = display.newRect(0,0, 10,10)  
obj:setFillColor(255, 0 , 0)  
obj.x = display.contentWidth / 2  
obj.y = 30  
  
physics.addBody(obj, "static")  
obj.isBullet = true  
  
local target = display.newRect(0,0, 10,10)  
target.x = display.contentWidth / 2  
target.y = 430  
physics.addBody(target, "static")  
target.isSensor = true  
  
local function targetCollision(e)  
 if e.phase == "began" then  
 print("Collision occurred")  
 target:removeSelf()  
 target = nil  
 end  
end  
target:addEventListener("collision", targetCollision)  
  
local function objForce(e)  
 if e.phase == "began" then  
 obj.bodyType = "dynamic"  
 obj:applyForce(0, 0.9, obj.x, obj.y)  
 end  
end  
  
obj:addEventListener("touch", objForce)

If I set target.isSensor = fase the collision happen but the obj may bounce sometimes.

Any solution to this? Thank you.

Hi Steve,

As just a trying, what if between the lines 26 and 27 you insert something like:

[lua]return true[/lua]

Nothing change?

Best of luck!

Hi Rodrigo,

It doesn’t make any difference because the code block has never been called. Thank you.
