Preventing clipping through walls and be invincible.

[StandarsForDeca]

Years ago there were several spots where you could walk into a wall like it wasn't there and kill monsters safely while in there. They follow you up to in front of that wall, like if they knew where you are, but once they get there they just stand there unable to attack you and thus are easy exp.

The third column of Lost Tower 4 comes to mind, now fixed in Global Mu.

There was also a wall in LT3 but forgot the coordinates.

My question is how do i prevent players on my server from exploiting this? Is this a server sided problem, or a problem with the client of the player and thus i need to patch the map with a new version of it?

More importantly, i only knew of the LT wall clip but dont know about other maps. Are there others spot i should be wary off on other maps and patch ASAP?

if im not wrong you can solve that just by editing the maps terrains in the client side

[StandarsForDeca]

How do i do that? Also, is this problem related to an old bug in Global Mu where you can walk INTO a frozen lake in central Devias, and if you go further you get warped to Lorencia? Or is this like 2 different bugs working together? What version was that anyway? cant remember.

Wait a second, did you say "client side"? Pardon me if i am wrong, but doesnt that mean that even if i edit and release a patch fixing the terrains for all my players, they can get an editor and change it back since they can affect it on THEIR side, the client side?

Use pentium tools or world editor
about if if is the same bug as GMO im not sure, i said the terrains thing since that controls where you can walk
pack the edited files to avoid the users editing them
