You can use MapRange node like so:
The light is initially set to 5000 and the slider to 0.5. That’s assuming you want a 0-10000 range, for example.
Moreover like you see from my
screenshot I have a level
blueprint,alt text where I can open
another interface with “Z” and I able
to control button there with keyboard.
I would integrate my slider there, or
simply call with the same letter the
slider.
Try to avoid doing stuff in the Level Blueprint (LB), there’s usually hardly any need for that. Especially things like input. Input should be in the Player Controller or Pawn. What if you go to level 2, your inputs will stop working and you will need to duplicate all the code for each level… It’s ok if you’re just learning but placing input in actors and level blueprint will make it difficult to debug when things get complicated.
It’s difficult to advise as it’s hard to say what you’re planning on making. If you’re just messing about with the editor to learn the ropes, ignore my naysaying and do not let anyone stop you!
