PopState[edit]
Pops the current pushed state, returning execution to the previous state at the same code point. Note: PopState() will have no effect if no state has been pushed onto the stack.
This will call PoppedState when entering the state that was just pushed on the state stack. It will not call EndState.
Parameters:
- bPopAll - optionally pop all states on the stack to the originally executing one
See: event PausedState
PushState[edit]
Pushes the new state onto the state stack, setting it as the current state until a matching PopState() is called. Note that multiple states may be pushed on top of each other. You may not push the same state multiple times.
This will call PushedState when entering the state that was just pushed on the state stack. It will not call BeginState.
Parameters:
- NewState - name of the state to push on the stack
- NewLabel - optional name of the state label to jump to
See: event ContinuedState
SaveConfig[edit]
TimeStamp[edit]
Returns a string containing a system timestamp
TransformVectorByRotation[edit]
Script hook to FRotationMatrix::TransformFVector().
Events[edit]
BeginState[edit]
Called immediately when entering a state, while within the GotoState() call that caused the state change (before any state code is executed).
ContinuedState[edit]
Called on the state that is no longer paused because of a PopState().
EndState[edit]
Called immediately before going out of the current state, while within the GotoState() call that caused the state change, and before BeginState() is called within the new state.
PausedState[edit]
Called on the state that is being paused because of a PushState().
PoppedState[edit]
Called immediately in the current state that is being popped off of the state stack, before the new state is activated.
PushedState[edit]
Called immediately in the new state that was pushed onto the state stack, before any state code is executed.
