Re: Rotate body around a point

Trig is all very nice but the setAngle() function only takes one argument, the angle. How can I rotate a body around a point other than local 0,0? The only way i can see to do this is to destroy all the shapes on the body, recreate the shapes in the position that coresponds to where i want to rotate...

Rotate body around a point

Can i specify a point to rotate a body around in real time or can i only rotate it around its local 0,0 point?

Re: Make an object float up, like a balloon

Collisions seem fine so far with the way i'm using setVelocity. But i'll bear what you say in mind incase i come accross any issues. Thanks.

Re: Make an object float up, like a balloon

But gravity is an continuous and accumulative force, so things that are falling accelerate. So I need the velocity to increase continuously, thats why i'm adding or subtracting 10 to the y velocity each frame depending on weather it's a riser or a faller. Giving the force just once on load wont have...

Re: Make an object float up, like a balloon

Cheers robin,

this is what i've come up with. works good enough for me:

Code: Select all

for i = 1, #bodies do
	local x, y = bodies[i].body:getVelocity()
	if bodies[i].fall then
		bodies[i].body:setVelocity(x, y+10)
	else
		bodies[i].body:setVelocity(x, y-10)
	end
end
Inside the update function.

Re: Make an object float up, like a balloon

That would be tricky, because i'd have to move any stationary platforms down with the view too.
I'm begining to think I might need to have zero gravity and accelerate the objects myself, some up, some down.
Does anyone know some love code for a psudo gravity function?

Make an object float up, like a balloon

Hey everyone, In my world I want some objects to fall, but other objects to rise up. I've tried using negative mass on some objects, but they dont move at all if their mass is negative unfortunately. Another option would be to create two worlds, one with gravity set in the opposite direction to the ...

Re: Number of Joystick Axes

Thanks bartbes. I've made something similar myself though.
