◆ GetCustomRoadSprite()

SpriteID GetCustomRoadSprite	(	const RoadTypeInfo *	rti,
		TileIndex	tile,
		RoadTypeSpriteGroup	rtsg,
		TileContext	context,
		uint *	num_results
	)

Get the sprite to draw for the given tile.

Parameters

	rti	The road type data (spec).
	tile	The tile to get the sprite for.
