Basic gravity problems

Getting Started Newbie Questions
#1

Hi,

Default gravity is “9.8” which should match earths gravity. But honestly, objects are falling far slower than in reality. Setting the gravity to around 40 (or gravityScale = 4) gives a much more realistic feeling, but causes objects to collide endlessly with the ground (they never fall asleep).

So here are my questions:

  • Why do the default gravity settings feel like we’re on the moon, even though they use “values like in real world”?
  • Does anybody have settings that improves the physics behaviour?

That’s everything so far.

Depends how you define your objects.

#3

Basic object, default values, like in the Corona “Physics Based Game” Template Project. E.g: 

physics.addBody( crate, { density=1.0, friction=0.3, bounce=0.3 } )
#4

The thing to check is how high you’re dropping objects from. It may be a lot higher than you think - as far as “real world” goes. So high that the acceleration is clearly visible, whereas in your front room it would not be.
