In this recipe, we will add a stamina display to an interface for use with the sprint system previously implemented in Recipe #5 - Sprint with Stamina (Using Statistics).

Requirements

• A stamina system, as previously described in Recipe #5.
  
• An interface for your HUD elements.
  
• (Optional) An icon for your Sprint statistic.

Setup

1. After opening your project, select Interfaces in the lower left to list your interfaces.
   
2. Open your HUD interface.
   
   1. Using the Graph tool, add a field to the interface. Don't worry about where you place it, you can adjust it later.
      
      
      1. In the field's Use Value settings, click on the box beside Retrieve Value.
         
         1. Select Current Statistic under the Actor category.
            
            1. Select (Main) for Actor and Stamina for Statistic.
               
            2. Click OK to close the window.
               
      2. Also in the field's Use Value settings, click on the box beside Retrieve Maximum.
         
         1. Select Maximum Statistic under the Actor category.
            
            1. Select (Main) for Actor and Stamina for Statistic.
               
            2. Click OK to close the window.
               
      3. Style the field however you like. 
         
         1. The Shape option under Behavior allows you to switch your field between Pie, Bar, and Rotating Dial modes. Bar probably makes the most sense for this field, but you can use whichever you prefer.
            
         2. Click OK to close the window. You can move and resize the field with the Pointer tool in the interface editor.
   2. If you have added an icon to your statistic:
      
      1. Using the Field tool, add a text field somewhere near your graph.
         
         1. Click on the use value box next to Retrieve Text under the Use Values section.
            
            1. Select Graphic under the Statistic category.
               
               1. Select Stamina for Statistic.
                  
               2. Click OK to close the window.
         2. Click OK to close the field window.
      2. This text field will now display the graphic that you previously assigned to the Stamina statistic. If there is no graphic assigned to that statistic, it will display a white square instead.
3. Test out your new interface!

Notes

If you're using a template, your game probably already has a default HUD interface. If you're not (or you've created your own interface), you can add one by selecting it in the Default HUD list under Interfaces in the Game Settings window.
