i cant upload the capx, ive stripped pretty much everything from the game that is decorative, shrunk the layout sizes, shrunk and reduced the amount of sprites in the current area and it STILL wont go below 3.78 MB, the max upload limit is 2MB.
I'll try to explain it as best i can:
In terms of the effect im using on the player, it is identical to the boat.capx effect that you linked me, all the coding is the same.
The wall has only solid and shadow caster behaviors on them, the player has scroll to, 8 direction and bind to layout behaviors, while the doors have Solid and Shadowcaster too. everything apart from the player bound to layout is identical in terms of behaviour. as for the code itself, it is also the same as the boat game as it had worked at first
as for the game itself, the player can see through the shadow cast by the walls when they're close to said wall, this makes it so that the player can see through the wall. As well as being able to see through the wall, the player can see the doors through the shadows as well, although it is like that on the boat game and i could incorporate that into my game if needed.
If i haven't explained it well let me know and i'll try again eli0s
