Blueprint value debugging

When trying to figure out the unreal interface I hit play on one of the demos and saw the values (input values) going through the blueprint editor as I was playing the game. This made analyzing the blueprint extremely easy, and would also be extremely valuable for debugging. Unfortunately, I can’t figure out how to do it again…

For example, when I pushed the up arrow in this demo the float value from InputAxis MoveUp was being shown in the blueprint script editor.

Any ideas?


If you have multiple of the same class active then the debugger doesn’t know which one to select. After clicking play you can alt-tab to your blueprint and in the top you should see a dropdown that contains the active actors. Choose the one you want to see and everything should update.

If an actor of the type is in a level then selecting that actor should(i think) be auto-chosen to debug.
