changing tileset passability
 

Does anyone know how to change tiles' passability? Not the normal database way, but with an event or something. Cuz I was wanting to make an item that lets you walk underwater. And also, when you go underwater, the hero turns transparent, so the hero looks likes he's underwater.(REALLY?! NO WAY! He looks like he's underwater when he IS underwater?)

need to do more than what I'm saying for the item, but I'm lazy right now. To get your hero to look like he's underwaater, add a blue square to your tileset.(32x32) When importing make blue transparent. Now you can be as blue as you want.(making the blue darker makes it more opaque)

You're using RMXP, right? The only way I can think of to surround all bodies of water with clear events that you can't walk on without an item. In other words, a blank page 1, no preconditions, with a blank tile set to unpassable - then on page 2, the precondition is that some switch is activated (can't base it on the item itself - RMXP removed that ability), and the picture is a blank tile that you CAN walk over.

As for transparency, I'd say to just set that in the Terrain tab - but RMXP removed that functionality. Oh boy. Best thing is indeed to have a faux-transparent blue "filter" tile on top of all bodies of water (on the highest layer) - have it set to be above the hero, and don't "filter" the southernmost tiles of any bodies of water so you can walk on the shore below it without having your head look like it's underwater.

Huh? What? Can you make a demo, cuz that was just confusing.

Methinks I get what he's on about.

If no-one has made a demo before 3pm tomorrow (my time - about 5 hours ahead... so 10am your time) I'll have a crack at it.
