# Class "Room"

## Functions

### CheckLine () {: aria-label='Functions' }

[ ](/ab_p/beta/docs/room.md){: .abp .tooltip .badge }

#### boolean CheckLine ( [Vector](https://github.com/wofsauge/IsaacDocs/tree/420a6aaa54ea230461fb26e61297c068492684de/beta/Vector/README.md) Pos1, [Vector](https://github.com/wofsauge/IsaacDocs/tree/420a6aaa54ea230461fb26e61297c068492684de/beta/Vector/README.md) Pos2, LinecheckMode Mode, int GridPathThreshold, boolean IgnoreWalls, boolean IgnoreCrushable ) {: .copyable aria-label='Functions' }

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

???- note "Notes" 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

#### [Vector](https://github.com/wofsauge/IsaacDocs/tree/420a6aaa54ea230461fb26e61297c068492684de/beta/Vector/README.md) ScreenWrapPosition ( [Vector](https://github.com/wofsauge/IsaacDocs/tree/420a6aaa54ea230461fb26e61297c068492684de/beta/Vector/README.md) Pos, float Margin ) {: .copyable aria-label='Functions' }

Returns Pos, screen-wrapped (if it is just outside the room on the right it will be moved to the left side of the room, etc)

???- note "Notes" This only wraps the point once, so if it has crossed multiple wrapping planes it will only wrap on the one it's closest to. For wrapping a position that has crossed two planes (outside a room in the top left for instance) call this function iteratively.
