Pie nodes are used to create circular or ellipsoid objects ranging from plain circles to pies and square donut shapes.
Right click the Nodes section in the Outline and select Add ▸ Pie. The new pie node is selected and you can modify its properties.
The following properties are unique to pie nodes:
The inner radius of the node, expressed along the X axis.
The shape of the outer bounds of the node.
Ellipsewill extend the node to the outer radius.
Rectanglewill extend the node to the node’s bounding box.
The number of segments that will be used to build the shape, expressed as the number of vertices required to fully circumscribe the 360 degree perimeter of the node.
How much of the pie should be filled. Expressed as a counter-clockwise angle starting from the right.
If you set a texture on the node, the texture image is applied flat, with the corners of the texture correlating to the corners of the node bounding box.
Pie nodes respond to any generic node manipulation functions for setting size, pivot, color and so forth. A few pie node only functions and properties exist:
local pienode = gui.get_node("my_pie_node") -- get the outer bounds local fill_angle = gui.get_fill_angle(pienode) -- increase perimeter vertices local vertices = gui.get_perimeter_vertices(pienode) gui.set_perimeter_vertices(pienode, vertices + 1) -- change outer bounds gui.set_outer_bounds(pienode, gui.PIEBOUNDS_RECTANGLE) -- animate the inner radius gui.animate(pienode, "inner_radius", 100, gui.EASING_INOUTSINE, 2, 0, nil, gui.PLAYBACK_LOOP_PINGPONG)
