Well well well, it seems that my blueprint for one of my lights works :
At least, it seem to do the trick, but I don’t know why, I have an error everytime I stop the simulation “Accessed none. Trying to read property K2Node_DynamicCastAsThird_Person_Character”. It do that for the branch and the “set overlap light” above. Any idea why ? Except that error, it seem to work fine. And if I plug the “Set overlap light” in the “True” of the branch, the error doesn’t appear, but then again, when I turn off the light while overlapping, the progress bar goes down.
If any question, just ask, this bp might be a bit “dirty” x)
