Local Variables
Store your progress per scene
Local Variables are one of the most useful Game Creator tools. They allow to access different variable instances from different game objects but with the same name.
For example, let's say you want to give each character of your game a unique name. You can create a Local Variables component on each one of them and create a local variable called name.
When accessing it, each character will return its own unique name.
Local Variables work pretty much like Global Variables. The difference is that they live inside the scope of a game object, not project wide.
Creating and Editing
To create a local variable you can add the Local Variables component to any game object. Alternatively you can create one using the Game Creator Toolbar option to create a new instance.
Notice there's a UID field at the end of the component. This UID is used by the save-system to keep track of the different variables between play sessions.
Every time you create a Local Variable, a unique UID is generated. You have to bear in mind though that when duplicating a Local Variable, this value will stay the same and two Local Variables will exists with the same UID. In that case, click on the R button to generate a new unique button.
It is specially important that you don't modify the UID after releasing your game. Doing so will reset the player's game progress.
You can also modify the UID value with a more descriptive one, as long as they are unique.
Nested Access
Since version 0.9.7 you can access nested Game Object variables. For example, if a Local Variable A has a reference to another Game Object B that also contains a Local Variable, you can access the Local Variable B by adding a "slash" character between the names of both variables.
Game Object 1 has Local Variable "myVariableA" with Game Object 2 as its value
Game Object 2 has Local Variable "myVariableB" with an arbitrary value
Accessing via the above name will return the value of the second Local Variable.
Saving Variables
Just like Global Variables, Local Variables have a little checkbox next to its name field. Marking it will tell Game Creator that this variable value must be tracked between play sessions.
Prefabs can't save the value of any type of variable because there can be any number of prefab instances in a scene at any given point.
