love.physics.newMouseJoint
Create a joint between a body and the mouse.
This joint actually connects the body to a fixed point in the world. To make it follow the mouse, the fixed point must be updated every timestep (example below).
The advantage of using a MouseJoint instead of just changing a body position directly is that collisions and reactions to other joints are handled by the physics engine.
Function
Synopsis
joint = love.physics.newMouseJoint( body, x, y )
Arguments
Body body
- The body to attach to the mouse.
number x
- The x position of the connecting point.
number y
- The y position of the connecting point.
Returns
MouseJoint joint
- The new mouse joint.
Examples
function love.load() world = love.physics.newWorld(0, 0) body = love.physics.newBody(world, love.mouse.getX(), love.mouse.getY(), "dynamic") shape = love.physics.newCircleShape(20) fixture = love.physics.newFixture(body, shape) joint = love.physics.newMouseJoint(body, love.mouse.getPosition()) end function love.draw() love.graphics.circle("fill", body:getX(), body:getY(), shape:getRadius()) end function love.update(dt) joint:setTarget(love.mouse.getPosition()) world:update(dt) end
