Player Input

Type: Exec (In → Out)
Category: PLAYER

Reads the keyboard and mouse every frame and stores the normalized state in _pi_* variables on the object. It is the first node in the player pipeline — connect it directly to OnUpdate.

Published state (_pi_*)

Variable	Type	Description
_pi_move_x	float	Lateral axis: −1 (left), 0, +1 (right)
_pi_move_y	float	Forward axis: −1 (back), 0, +1 (forward)
_pi_is_moving	bool	True while any movement key is active
_pi_sprint	bool	True while Sprint key is held (.active)
_pi_jump	bool	True only on the frame Jump was pressed (.activated)
_pi_fire	bool	True only on the frame Fire was pressed (.activated)
_pi_reload	bool	True only on the frame Reload was pressed (.activated)
_pi_slot_changed	bool	True only on the frame the active slot changed
_pi_slot	int	Current active slot index (0–9)

!!! note ".activated vs .active" - .activated → True for one frame only (rising edge, equivalent to "just pressed"). - .active → True while held down (continuous).

`_pi_sprint` uses `.active`; everything else uses `.activated`.

Typical usage

[OnUpdate] → [Player Input] → [Player Jump] → [Player Movement] → ...

All nodes that need to know whether the player is moving, jumping, firing, etc. must be on the same object as this node and read their corresponding _pi_* variables.

Notes

• Inventory slot state (0–9) can also be changed with the mouse wheel when Slot: Scroll Wheel is enabled.
• _pi_fire is also exposed as self.input_fire for compatibility with Weapon Fire Executor.
