Collision detection failing from time to time

Solar2D General Questions/Discussion
#1

In my game, I have a physical object (with the property isSensor set to “true”) that I want to overlap some other physical object, and I want to verify it’s collision with other objects and setup some specific actions based on the result. But from time to time, even if I see in the simulator two objects overlapping, the terminal tells me that the collision ended (I made it print the phase status, “began” or “ended”). How can I resolve this issue?

I’ve tried setting the “isBullet” property to “true”, but that hasn’t made much of a difference. (By the way, what does this do exactly?)
I’ve thought about putting the collision listener inside an “enterFrame” listener, so that the collision is verified periodically, but imagine the performance drop resulting from this… It’s not a valid answer.

Any ideas? [import]uid: 13720 topic_id: 5708 reply_id: 305708[/import]

Show the code mate else it’ll be very hard to tell you what’s wrong / what to fix

Have you tried (myBody).isSleepingAllowed = false? Maybe your bodies are going to sleep [import]uid: 30185 topic_id: 5708 reply_id: 19539[/import]

#3 
senzor = display.newRect(322, 502, 20, 50)  
 senzor:setFillColor(255,0,0)  
 senzor.alpha = 0 -- so that it's invisible  
 physics.addBody(senzor,"dynamic",{density=0, friction=1, bounce=0.3})  
 senzor.class = "senzor" -- useful for an if-statement later  
 senzor.isSensor = true -- so that it doesn't physically interact  
 senzor.angularDamping = 5000 -- to keep ot from rotating around

And the collision detector…

local touched = false  
local function touchedFunc(self, event)  
 if ( event.phase == "began" ) then  
 touched = true  
 elseif ( event.phase == "ended" ) then  
 touched = false  
 end  
end  
senzor.collision = touchedFunc  
senzor:addEventListener( "collision", senzor )

And this “sensor” is attached to another object by a “pivot” joint. It’s supposed to detect collision and report it to another function, so that the function does it’s stuff or not. I already tried the isSleepingAllowed one, doesn’t help at all… [import]uid: 13720 topic_id: 5708 reply_id: 19608[/import]
