Here is what I did:
- I created an empty project
- I added Inputs in the project settings
- I created a character Blueprint and configured the input events in the Event Graph
- I created a Gamemode Blueprint that uses that character Blueprint and set it as the default Gamemode.
When I hit play I can do some basic flying movement (I set my Character Movement Component to flying). However an input event I created is not working and I do not see any Blueprint events firing in the Character Blueprint Event Graph - not even the On Begin Play event was firing when I tried out if I had to enable input.
I replicated my Input configuration inside another project using the First Person Template and there it works flawlessly. I compared the settings of both projects and their blueprints but nothing helped.
Edit:
Now I imported a map I created from my empty template project to my first person template project. Neither my modified First Person Character Blueprint with First Person Gamemode nor My Character Blueprint with My Gamemode work on the custom map. Neither does My Character Blueprint with My Gamemode work on the First Person Template Map. Only the First Person Character Blueprint with the First Person Gamemode on the First Person Template Map works.
Edit2:
I guess the source of the problem might be the differentiation between the player start and an instance of the CharacterBlueprint. In the First Person Template Map the player is spawned at the location of such an instance which is not the case for my map.
