Direction
Functions
angleToDirection
▸ angleToDirection(angleDegrees): Direction
Helper function to convert the degrees of an angle to the Direction enum.
Note that this function considers 0 degrees to be pointing to the right, which is unusual because
0 normally corresponds to up. (This corresponds to how the Vector.GetAngleDegrees method
works.)
Parameters
| Name | Type |
|---|---|
angleDegrees | int |
Returns
Direction
Defined in
packages/isaacscript-common/src/functions/direction.ts:16
directionToDegrees
▸ directionToDegrees(direction): int
Helper function to convert a direction to degrees. For example, Direction.LEFT (0) would return
180 and Direction.RIGHT (2) would return 0. (This corresponds to how the
Vector.GetAngleDegrees method works.)
Parameters
| Name | Type |
|---|---|
direction | Direction |
Returns
int
Defined in
packages/isaacscript-common/src/functions/direction.ts:47
directionToMoveAction
▸ directionToMoveAction(direction): ButtonAction | undefined
Helper function to convert a direction to a shoot ButtonAction. For example, Direction.LEFT
(0) would return ButtonAction.LEFT (0).
Parameters
| Name | Type |
|---|---|
direction | Direction |
Returns
ButtonAction | undefined
Defined in
packages/isaacscript-common/src/functions/direction.ts:55
directionToShootAction
▸ directionToShootAction(direction): ButtonAction | undefined
Helper function to convert a direction to a shoot ButtonAction. For example, Direction.LEFT
(0) would return ButtonAction.SHOOT_LEFT (4).
Parameters
| Name | Type |
|---|---|
direction | Direction |
Returns
ButtonAction | undefined
Defined in
packages/isaacscript-common/src/functions/direction.ts:65
directionToVector
▸ directionToVector(direction): Readonly<Vector>
Helper function to convert a direction to a Vector. For example, Direction.LEFT (0) would
convert to `Vector(-1, 0).
Parameters
| Name | Type |
|---|---|
direction | Direction |
Returns
Readonly<Vector>
Defined in
packages/isaacscript-common/src/functions/direction.ts:75
getDirectionName
▸ getDirectionName(direction): string | undefined
Helper function to get the lowercase name of a direction. For example, Direction.LEFT (0) would
return "left".
Parameters
| Name | Type |
|---|---|
direction | Direction |
Returns
string | undefined
