In the previous lesson, you used a predefined member variable named [code]position[/code]. In your projects, you will need to define your own variables. Imagine that you need to track the player's health in your game. They may start with [code]5[/code] health points. When taking a hit, the health should go down to [code]4[/code]. After another hit, it should be [code]3[/code]. And so on. To keep track of that, you can create a variable named [code]health[/code] to which you add and subtract points. The example below introduces the [code]print()[/code] function, which outputs its argument to the output box on the left. Click the [i]run()[/i] button to instantly run the entire function, and click the [i]step[/i] button to execute lines of code one by one. The [i]Debugger[/i] panel at the bottom shows the current value of the [code]health[/code] variable.
