Enumeration Type Documentation

PersistentStorageMode

enum PersistentStorageMode

Mode switches to the behaviour of persistent storage array.

Enumerator
PSM_ENTER_GAMELOOP	Enter the gameloop, changes will be permanent.
PSM_LEAVE_GAMELOOP	Leave the gameloop, changes will be temporary.
PSM_ENTER_COMMAND	Enter command scope, changes will be permanent.
PSM_LEAVE_COMMAND	Leave command scope, revert to previous mode.
PSM_ENTER_TESTMODE	Enter command test mode, changes will be temporary.
PSM_LEAVE_TESTMODE	Leave command test mode, revert to previous mode.

Function Documentation

AddChangedPersistentStorage()

void AddChangedPersistentStorage

(

BasePersistentStorageArray *

storage

)

Add the changed storage array to the list of changed arrays.

This is done so we only have to revert/save the changed arrays, which saves quite a few clears, etc. after callbacks.

Parameters

storage

the array that has changed
