To be fair to the author, it looks like you have to iterate though all layers of all tiles in a given scene to find the tile tags from the current RPGMZ APIs so solving this is a bit more challenging and probably needs a more efficient way to approach this i.e. needs to iterate once per scene start and cache tile references with tags in some type of hash map or look up table to make this more efficient. I was thinking about doing it and sharing the code but not a lot of time currently and I am forcing myself to finish a short game I am working on right now
