How would one create an object, like for instance, a blood splatter or puddle that can be walk over by characters? I see there's an 'Always on Top' but not an 'Always on Bottom'so I'm wondering if there isn't another way. I know I can make other objects 'Always on Top' but that isn't a preferable solution for the map I'm working on. Thank you all in advance

The option directly above "Always on top" should say "Through", just check that box and you'll be able to move over the event no problem. The only problem would be if you stand behind it (one square above it on the map) it could overlap your hero event if the blood splatter's graphic is too tall. Try it out though, hope this helps

Hello! Thats a very good question. I got 2 ways around this - you can try whenever way you think is the best for you:

The simple way: edit your tileset and add blood effects to the tileset's existing ground tiles. .

The other way: for in case you want to keep the blood separated from the tileset's existing ground tiles. In this case, the blood should, again, be added to your tileset, like I described in the above simple way, BUT, not on existing tiles! The blood to be new tiles in the tileset.
Then go to your map you want to use the blood, and create new events on that spot where you like to have the blood splatter to be placed at. And them to use the blood tiles as their graphic. Also check on Passability of the event. Now the blood should be passable and also below the player.

Thank you both for you answers.
