Hi Asmodean.. thankyou so much.. it works! Awesome !
the "disable/enable collision with.." is magic :D
Anyway.. I want to understand it more about what "System Trigger once" do here ?
Is that to prevent system keep checking the velocity ?
So.. once Pig velocity.Y reach the requirement will trigger once Disable/enable collision, and never check the velocity.Y anymore althought the physics still not in sleep mode ?
Or it actually keep checking all the time when the pig physics not in sleep mode, and stop checking once it reach sleep mode (velocity X and velocity Y = 0 ) ? I assume the velocity.Y always changing since the piggy in moving mode (impulse)
