Low Gravity #145

I'm curious about this as well. A simple fix would be to run applyForce in the animate function.

body.applyForce(
 new CANNON.Vec3(0, 10, 0), // force (not gravity)
 new CANNON.Vec3(0, 0, 0) 
)

@SuboptimalEng you mean to counter gravity?

Id rather not, if there is no option yet maybe it can be added as it should be rather simple

Just jumped into the code to see what you meant. If I understand it correctly, a better option could be to add body.type like ZERO_GRAVITY and update the internalStep function to handle it.

I'm super new to this btw. Started learning Cannon.js + game dev physics two days ago.

Hey! To make only an object appear gravitless, you have to apply an equal and opposite force to the object before each step.

const world = new CANNON.World()
world.gravity.set(0, -9.81, 0)
const body = ...
world.addEventListener('preStep', () => {
 body.applyForce(new CANNON.Vec3(0, 9.81, 0)) // opposite of gravity 
})
