How do i make custom variables

  1. Click “Add New” in your content browser.
  2. Select “Blueprints” → “Structure”.
  3. Type a name for your struct.
  4. Double click on your new struct and add included types.
  5. In your Blueprint you can now add that struct as a variable type.
  6. You struct will appear under the “Structure” section when you select a variable type, see here https://docs.unrealengine.com/latest/INT/Engine/Blueprints/UserGuide/Variables/Structs/index.html#creatingstructs for information on how to select the struct, split the struct, etc…

Hope that helps.
