You can create a new variable from any data pin by using the right click option ‘Promote to Variable’, which will automatically be hooked up to read/write it. These gems are well worth learning, so here is a cheat sheet of controls, keyboard shortcuts, and some useful actions:Ĭlick to download: Color Version | Black/White Version Fun with variables The blueprint editor has a lot of productivity boosting shortcuts built-in, and while many will come naturally as you use the editor, others are a little bit hidden. Almost anything can be searched, including references to a variable or function, comments, literal values, etc… There are also shortcuts to search for function and variable references in the context menu for your variables and user defined functions. You can search in the current blueprint or in all blueprints in your project (even unloaded blueprints!) using Ctrl+F or Ctrl+Shift+F. You can also disable the filtering in the action menu using the check box on the top right, but don’t forget about it, since it will stay unfiltered until you check the box again. You can drag-and-drop nodes from the palette into the graph, just like you can drag your custom functions from the My Blueprint list. The palette exists to help when you come up with the action before the target it isn’t filtered by context and contains all possible actions. You need a specific object before you can see actions for that object (e.g., you need a static mesh component before you can look for SetStaticMesh).
This filtering helps you find actions and place nodes quickly, but it requires a bit of forward planning that doesn’t always match the way you think when solving a problem. The current context filter is always displayed at the top of the action menu, which can be helpful if you don’t see something you were expecting to find.
Similarly, if you drag off of a pin and let go on the graph background, the action menu will be filtered to actions that take or provide a value matching the pin type and direction. If you right-click on a blueprint graph, you’ll get a list of actions that make sense in the context of the current blueprint and graph.įor example in an Actor based blueprint, you’ll get offered actions that target an Actor, as well as ones that work in any context. When you’re working with the blueprint editor, it’s important to remember that context is king.
