Selecting Blocks

There are several ways to do it.

We will be using style below to mark selected area by triangles.

@tool
class_name AllPrismStyle
extends RoommateStyle


func _build_rulesets() -> void:
    var ruleset := create_ruleset()

    ruleset.select_all_blocks()

    var all_parts := ruleset.select_center()
    all_parts.invert_selection()

    var prism := PrismMesh.new()
    prism.size = Vector3(1, 1, 0.05)
    all_parts.mesh.override(prism)

Selecting All Blocks

If you want to change all the blocks in RoommateRoot, you can add RoommateStyler and set it's style.

Selecting Blocks With Blocks Areas

You can use RoommateBlocksArea and set style and set it where you want. In this example, We changed quarter of the room to triangles.

You can actually do the same with RoommateSpace, but RoommateBlocksArea doesn't create any blocks, so it's more convenient.

Selecting Blocks Dynamically Using Style's Blocks Selectors

You can change block selection . For example, here we selecting farthest block along Z axis.

@tool
class_name AllPrismStyle
extends RoommateStyle


func _build_rulesets() -> void:
    var ruleset := create_ruleset()

    # NEW!!
    ruleset.select_blocks_by_extreme(Vector3.FORWARD)

    var all_parts := ruleset.select_center()
    all_parts.invert_selection()

    var prism := PrismMesh.new()
    prism.size = Vector3(1, 1, 0.05)
    all_parts.mesh.override(prism)

You can set this style to RoommateBlocksAreas. Selection will be limited to blocks that this area encompases.

You can also merge together multiple selectors with different modes

ruleset.select_blocks_by_extreme(Vector3.FORWARD).include()
ruleset.select_all_blocks().invert()
