◆ LE_IsLocked()

bool LE_IsLocked ( int entnum )

Checks if a given le_t structure is locked, i.e., used by another event at this time.

Parameters

entnum the entnum of the le_t struct involved.

Returns: true if the le_t is locked (used by another event), false if it's not or if it doesn't exist.

◆ LE_IsOriginBrush()

bool LE_IsOriginBrush ( const le_t *const le )

inlinestatic

Origin brush entities are bmodel entities that have their mins/maxs relative to the world origin. The origin vector of the entity will be used to calculate e.g. the culling (and not the mins/maxs like for other entities).

Parameters

le	The local entity to check

Returns: true if the given local entity is a func_door or func_rotating

◆ LE_Lock()

void LE_Lock ( le_t * le )

Markes a le_t struct as locked. Should be called at the beginning of an event handler on this le_t, and paired with a LE_Unlock at the end.

Parameters

le	The struct to be locked.

Note: Always make sure you call LE_Unlock at the end of the event (might be in a different function), to allow other events on this le_t.

◆ LE_Think()

void LE_Think ( void )

◆ LE_Unlock()

void LE_Unlock ( le_t * le )

Unlocks a previously locked le_t struct.

Parameters

le	The le_t to unlock.

Note: Make sure that this is always paired with the corresponding LE_Lock around the conceptual beginning and ending of a le_t event. Should never be called by the handler(s) of a different event than the one that locked le. The owner of the lock is currently not checked.

Todo: If the event loop ever becomes multithreaded, this should be a real mutex lock.

◆ LET_SlideDoor()

void LET_SlideDoor	(	le_t *	le,

Slides a door.

Note: Though doors, sliding doors need a very different handling: because it's movement is animated (unlike the rotating door), the final position that is used to calculate the routing data is set once the animation finished (because this recalculation might be very expensive).

Parameters

[in,out]	le	The local entity of the inline model
[in]	speed	The speed to slide with - a negative value to close the door
