### Undo Redo System

```cs

JCS_UndoRedoSystem urs = this.GetComponent();

// Do undo once from this system if any.

urs.UndoComponent();

// Do redo once from this system if any.

urs.RedoComponent();

// Stop recording undo/redo action to all the component control 

// by this undo/redo system.

urs.StopRecrodingAll();

// Start recording undo/redo action to all the component control 

// by this undo/redo system.

urs.StartRecrodingAll();

// Record initialize data once to all undo/redo component.

urs.RecordPrevData();

/* Clear history */

{

    // Clear all undo history.

    urs.ClearUndoComp();

    // Clear all redo history.

    urs.ClearRedoComp();

    // Clear all the undo redo history data.

    urs.ClearAllUndoRedoHistory();

}

/* Check for undo redo action exists? */

{

    // Check if there is at least one undo history?

    bool undoData = urs.ThereIsUndoHistory();

    // Check if there is at least one redo history?

    bool redoData = urs.ThereIsRedoHistory();

    // Check if there is at least one undo/redo history?

    bool undoRedoData = urs.ThereIsUndoOrRedoHistory();

}

```

### Undo Redo Component

```cs

JCS_UndoRedoComponent urc = this.GetComponent();

// Do one undo to this component.

urc.Undo();

// Dp one redo to this component.

urc.Redo();

// Stop recording undo/redo action starting from this moment.

urc.StopRecording();

// Start recording undo/redo action starting from this moment.

urc.StartRecording();

// Is the current component recording undo/redo action now?

bool isRecording = urc.IsRecording();

// If the UI value have changed by script at initialize time 

// but the undo/redo component did not get the correct default 

// data from the UI call this manually will record down the UI 

// starting value.

urc.RecordPrevData();

/* Clear history */

{

    // Clear all undo history to this component.

    urc.ClearAllUndo();

    

    // Clear all redo history to this component.

    urc.ClearAllRedo();

    

    // Clear all undo and redo history to this component.

    urc.ClearAllUndoRedoHistory();

}
