Description

Joints that constrain bodies.

Synopsis

data Joint data JointType = Pin { anchor1 :: Position anchor2 :: Position } | Slide { anchor1 :: Position anchor2 :: Position minDist :: CpFloat maxDist :: CpFloat } | Pivot { pivot :: Position } | Groove { groove1 :: (Position, Position) pivot2 :: Position } newJoint :: Body -> Body -> JointType -> IO Joint

A joint represents a constrain between two bodies. Don't forget to add the bodies and the joint to the space. Instances Eq Joint Ord Joint Entity Joint

data JointType Source

There are currently four types of joints. When appending a number to a property, we hint that it refer to one of the bodies that the joint is contraining (e.g. anchor2 is the position of the anchor on the second body in its coordinates). Constructors Pin A pin joint connects the bodies with a solid pin. The anchor points are kept at a fixed distance. anchor1 :: Position anchor2 :: Position Slide A slide joint is similar to a pin joint, however it has a minimum and a maximum distance. anchor1 :: Position anchor2 :: Position minDist :: CpFloat maxDist :: CpFloat Pivot A pivot joint allows the bodies to pivot around a single point in world's coordinates. Both should be already in place. pivot :: Position Groove A groove joint attaches a point on the second body to a groove in the first one. groove1 :: (Position, Position) pivot2 :: Position Instances Eq JointType Ord JointType Show JointType

newJoint :: Body -> Body -> JointType -> IO Joint Source

newJoint b1 b2 type connects the two bodies b1 and b2 with a joint of the given type. Note that you should add the Joint to a space.
