CityBuilderCore.BuildingRotation Class Reference

Detailed Description

facade for an integer from 0 to 3 describing the 4 possible directions for a building
used for transforming points in and out of building rotation(keeps building origin the same while rotating size and visuals)

void	TurnClockwise ()
void	TurnCounterClockwise ()
Vector2Int	RotateOrigin (Vector2Int origin, Vector2Int size)
	calculates the rotated corner of a building from the placement origin so bottom left with rotation 2 returns top right corner can be used to get get the transform position from the origin
Vector2Int	UnrotateOrigin (Vector2Int point, Vector2Int size)
	inverse of RotateOrigin(Vector2Int, Vector2Int) calculates the bottom left origin from the transform corner
Vector2Int	RotateBuildingPoint (Vector2Int origin, Vector2Int point, Vector2Int size)
	rotates a point relative to the building(access points for example) used to transform points in the building(0|1, 1|1) into world points
Vector2Int	RotateSize (Vector2Int size)
	calculates the rotated size on the grid starting from the origin

GetRotation()

Quaternion CityBuilderCore.BuildingRotation.GetRotation ( )

abstract

returns the world rotation for the building visual

Returns

RotateBuildingPoint()

Vector2Int CityBuilderCore.BuildingRotation.RotateBuildingPoint ( Vector2Int origin, Vector2Int point, Vector2Int size )

abstract

rotates a point relative to the building(access points for example)
used to transform points in the building(0|1, 1|1) into world points

Parameters

origin	origin of the building in world space
point	point inside the building space
size	size of the building

Returns

rotated point in world space

RotateOrigin()

Vector2Int CityBuilderCore.BuildingRotation.RotateOrigin ( Vector2Int origin, Vector2Int size )

abstract

calculates the rotated corner of a building from the placement origin
so bottom left with rotation 2 returns top right corner
can be used to get get the transform position from the origin

Parameters

origin	origin point
size	building size

Returns

RotateSize()

Vector2Int CityBuilderCore.BuildingRotation.RotateSize ( Vector2Int size )

abstract

calculates the rotated size on the grid starting from the origin

Parameters

size

Returns

UnrotateOrigin()

Vector2Int CityBuilderCore.BuildingRotation.UnrotateOrigin ( Vector2Int point, Vector2Int size )

abstract

inverse of RotateOrigin(Vector2Int, Vector2Int) calculates the bottom left origin from the transform corner

Parameters

point
size

Returns
