Hi,
I’m new in Lime+Corona+Lua+Mobile (it’s a lot of things! :P). BTW I’m trying to follow the Lime tutorials on OutLaws site and I’m stuck on the tutorial 11.
It seems that the map:addPropertyListener( “IsPlayer”, onPlayerProperty ) it’ll never triggered, that will cause that the player variable will never filled and that will cause a nil player error.
My player tile has the correct properties and I’ve followed the tutorial step-to-step but I can’t go on.
can anyone help me?
thanks very much
best regards
PS: this is my code
