Wow! I feel like a broken record but again thank you so much for all this help! I made some changes and it’s working ALMOST perfectly! This plugin really is amazing!
The only problem I’m having now is fInterping the meter (needle).
Here I have my LightDetector_BP (top screenshot) and my FirstPersonCharacter (bottom)
Then, this is the function I use to move the meters inside of my WBP_Viewfinder.
I see in the screenshot you uploaded, you use eventTick to fInterp. I could understand doing that, but how would I get the target light value every tick if the detector is only moving based on change in distance? With that in mind, I don’t think the needle needs to move every tick, since the fInterp should make it look smooth regardless. However, this is how it’s moving with the current settings above:
I’ve only used fInterp for moving static meshes, so I don’t fully understand it. If I could just get a bit more of an explanation on how to use it, it should be the last of the issues. Thank you for documenting all of this useful information!
