RoofExtension

<- Back

RoofExtension is a def extension that adds a few custom behaviours for new roofs.

    public bool drawRoofShadow = true;
    public bool dealDamageOnCollapsed = true;
    public Color? roofOverlayColor = null;
    public CustomRoofGraphic customRoofGraphic = null;

CustomRoofGraphic is a wrapper class:

    // Drawing data
    public Vector2 drawSize = Vector2.one;
    public Vector3 offset = Vector3.zero;
    public AltitudeLayer layer = AltitudeLayer.Skyfaller;

    // Material data
    public string customRoofGraphicPath = null;
    public ShaderTypeDef customRoofGraphicShader = null;
    public Color customRoofGraphicColor = Color.white;
    public int renderQueue = 0;

How do I use this code?

This Def Extension is added to the RoofDef of the roof you want to add them to.

If you aren't sure if the RoofDef ALREADY has an extension (for example, if you think another mod will add their own), always use XPATH (xml patching) to add an extension, as there is already a PatchOperationAddModExtension to ensure they don't collide.

For example, on Vanilla Gravship Expanded:

<modExtensions>
	<li Class="VEF.Maps.RoofExtension">
		<dealDamageOnCollapsed>false</dealDamageOnCollapsed>
		<drawRoofShadow>false</drawRoofShadow>
		<roofOverlayColor>(0.3, 0, 0.4)</roofOverlayColor>
		<customRoofGraphic Class="VanillaGravshipExpanded.ColorableVacBarrierRoofGraphic">
			<!-- Draw data -->
			<offset>(0, 0, 0.5)</offset>
			<!-- Material data -->
			<customRoofGraphicPath>Things/Structures/RoofVacBarrier</customRoofGraphicPath>
			<customRoofGraphicShader>TransparentPostLight</customRoofGraphicShader>
			<!-- Normally used as the singular color for material, here we use it as a base/default color. -->
			<customRoofGraphicColor>(146,76,237)</customRoofGraphicColor>
		</customRoofGraphic>
	</li>
</modExtensions>
