Method Descriptions

Returns true if this shape is colliding with another.

This method needs the transformation matrix for this shape (local_xform), the shape to check collisions with (with_shape), and the transformation matrix of that shape (shape_xform).


Returns a list of contact point pairs where this shape touches another.

If there are no collisions, the returned list is empty. Otherwise, the returned list contains contact points arranged in pairs, with entries alternating between points on the boundary of this shape and points on the boundary of with_shape.

A collision pair A, B can be used to calculate the collision normal with (B - A).normalized(), and the collision depth with (B - A).length(). This information is typically used to separate shapes, particularly in collision solvers.

This method needs the transformation matrix for this shape (local_xform), the shape to check collisions with (with_shape), and the transformation matrix of that shape (shape_xform).


Returns whether this shape would collide with another, if a given movement was applied.

This method needs the transformation matrix for this shape (local_xform), the movement to test on this shape (local_motion), the shape to check collisions with (with_shape), the transformation matrix of that shape (shape_xform), and the movement to test onto the other object (shape_motion).

  • void draw ( RID canvas_item, Color color )

Draws a solid shape onto a CanvasItem with the VisualServer API filled with the specified color. The exact drawing method is specific for each shape and cannot be configured.
