Abstract base class for all 2D physics joints.
描述
Abstract base class for all joints in 2D physics. 2D joints bind together two physics bodies (node_a
and node_b
) and apply a constraint.
属性
方法
属性说明
float
bias = 0.0
When node_a
and node_b
move in different directions the bias
controls how fast the joint pulls them back to their original position. The lower the bias
the more the two bodies can pull on the joint.
When set to 0
, the default value from ProjectSettings.physics/2d/solver/default_constraint_bias
is used.
bool
disable_collision = true
If true
, the two bodies bound together do not collide with each other.
NodePath
node_a = NodePath("")
Path to the first body (A) attached to the joint. The node must inherit PhysicsBody2D
.
NodePath
node_b = NodePath("")
Path to the second body (B) attached to the joint. The node must inherit PhysicsBody2D
.
方法说明
Returns the joint's internal RID
from the PhysicsServer2D
.
