Member Function Documentation

CheckLine()

boolean Room::CheckLine	(	Vector	Pos1,
		Vector	Pos2,
		LinecheckMode	Mode,
		integer	GridPathThreshold,
		boolean	IgnoreWalls,
		boolean	IgnoreCrushable
	)

returns true if there is a direct line of sight between Pos1 and Pos2 returns false if the line is obstructed

LinecheckModes:

0 : makes the line check collide with anything that impedes ground movement
1 : is a cheaper version of 0, but is not as reliable
2 : is used for explosions, it only collides with walls and indestructible blocks
3 : is a line check that only collides with obstacles that can block projectiles

DamageGrid()

boolean Room::DamageGrid	(	integer	Index,
		integer	Damage
	)

Damage Grid Entities currently this concerns GridEntityPoop and GridEntity_Fire returns true if damageable entity was found (and possibly damaged) return false if not used by tears, bombs, some NPCs, etc

DestroyGrid()

boolean Room::DestroyGrid	(	integer	Index,
		boolean	Immediate
	)

calls DamageGrid internally to damage Poop/Fire removes rocks and opens secret doors returns true if something was destroyed returns false if not used for explosions mostly

EmitBloodFromWalls()

Room::EmitBloodFromWalls	(	integer	Duration,
		integer	Count
	)

FindFreePickupSpawnPosition()

Vector Room::FindFreePickupSpawnPosition	(	Vector	Pos,
		float	InitialStep,
		boolean	AvoidActiveEntities
	)

Starting from Pos, will try to find a free spawn position where a newly spawned pickup item will not collide with already spawned pickup items, or solid grid elements such as rocks, or pits The returned position will be aligned to the grid. If no free position is found, the original position (aligned to the grid) is returned.

FindFreeTilePosition()

Vector Room::FindFreeTilePosition	(	Vector	Pos,
		float	DistanceThreshold
	)

Finds the nearest free tile based on position Stops immediately if the tile sampled has a squared distance less than DistanceThresholdSQ

GetAliveBossesCount()
