I think what you're talking about is gravity. (I think.) If you change "world:setGravity(0, 700)" to "world:setGravity(0, 0)" does it do what you want it to?

Ah, I gotcha.
In that case it looks like you're not accounting for the origin of bodies being their center. If you change
Code: Select all
objects[howmany].body = love.physics.newBody(world, x, y, m, r)
to
Code: Select all
objects[howmany].body = love.physics.newBody(world, x + (width / 2), y + (height / 2), m, r)
you'll see that by offsetting them by 1/2, you make their mouse origin line up with their body center.
(You'll also need to change your ground position to
rectangle(world,0,0,600,0,650,50,0)).

In other words, if the width OR the height of the rectangle is negative, the shape does not get created properly.
My advice to you would be to rethink your code. You have a LOT of unused variables in there, and you do a lot in the draw function that should probably be done in the update function. Consider rewriting the project from scratch, and the bug will probably not recur.
A few tips:
love.mouse.isDown("r") == true can be stated as just
love.mouse.isDown("r"). By the same token,
love.mouse.isDown("r") == false can be said as just
not love.mouse.isDown("r").
love.draw() should concern itself only with drawing. The "thinking" part of your game should be done in love.update()
This can be rewritten:
Code: Select all
colours = {} -- boring table stuff
colours.r = {}
colours.g = {}
colours.b = {}
to this:
Code: Select all
colours = {
r = {},
g = {},
b = {}
}
I find it to be easier to read and maintain, personally.
