Functions

Thousands of copies of one mesh in one draw, each with its own transform, colour and custom data, through node.multimesh3d.

15 functions, 0 constants. Scripts reach it as multimesh3d::.

Acts on multimesh3d: those functions are also methods on the component's handle, without the node argument.

Functions

Argument kinds are the script values a call passes: node is a node handle, any a table or value of any kind, fn a callback.

function	acts on	what it does
`buffer(Node) -> [float]`	`multimesh3d`	Every instance as one flat list of floats in Godot's `MultiMesh.buffer` layout: 12 of transform in 3D or 8 in 2D, then 4 of colour and 4 of custom data.
`instance_color(Node, int) -> Color`	`multimesh3d`	The colour one instance draws in.
`instance_count(Node) -> int`	`multimesh3d`	How many instances the node holds.
`instance_custom_data(Node, int) -> Color`	`multimesh3d`	One instance's four floats of custom data, as a colour.
`instance_transform(Node, int) -> Transform3d`	`multimesh3d`	One instance's transform.
`instances(Node) -> [render::MultimeshInstance]`	`multimesh3d`	Every instance as the `multimesh` asset spells it, so `assets.save` writes a scripted layout into a file.
`populate(Node, render::PopulateOptions) -> [render::MultimeshInstance]`	`multimesh3d`	Godot's Populate Surface, and a row, a ring or a grid: the instances a layout would write, worked out from `seed`, returned in the `multimesh` asset's shape rather than set. `kind` is `render.POPULATE_SURFACE` with a `surface` node, `POPULATE_ROW` (`count`, `step`), `POPULATE_RING` (`count`, `radius`) or `POPULATE_GRID` (`counts`, `step`); `rotation`, `tilt` and `random_scale` vary each instance, as fractions, around `scale`.
`set_buffer(Node, [float])`	`multimesh3d`	Replace every instance from one flat list in the layout `buffer` answers in, for a Godot port that sets `buffer`. Building the list in a script costs more than one `set_instance_transform` per instance.
`set_instance_color(Node, int, Color)`	`multimesh3d`	The colour one instance draws in.
`set_instance_count(Node, int)`	`multimesh3d`	How many instances the node holds. Those below the count keep where they were; new ones are plain, at the node.
`set_instance_custom_data(Node, int, Color)`	`multimesh3d`	Four floats a material's shader reads for one instance, as a colour.
`set_instance_transform(Node, int, Transform3d)`	`multimesh3d`	Place one instance. A shear is kept, as the instance's `basis`.
`set_instances(Node, [render::MultimeshInstance])`	`multimesh3d`	Replace every instance with a list in the `multimesh` asset's shape.
`set_visible_instance_count(Node, int)`	`multimesh3d`	How many instances draw, from the first; -1 draws them all.
`visible_instance_count(Node) -> int`	`multimesh3d`	How many instances draw; -1 is all of them.
