How does model editing work?

[Parog]

You can also change non-solid things ( traps ) to other solid things ( stairs for example ) and you will still be able to climb on it. It all depends if the M2 you are switching it allows collision.

All maps / spell graphics / item graphics ( all of them ) / sky - are hosted clientside, you do not change them directly from the game files, but rather trick the game to load a new gamefile ( MPQ ) and gives it priority over the other MPQs ( the normal wow ones ) What that means is that your 2h_sword_epic2.m2 from the MPQ you created ( basically any object renamed to 2h_sword_epic2.m2 ) will be loaded instead of the normal 2h_sword_epic2.m2 when you start WoW with MEF.

Hope that wasn't too confusing.

To answer your question, the solidness of an item is defined by the item itself. It will be solid whenever it is "summoned" no matter where it is. The server does not get any request to make it solid as it already is.

I'd really like to know how you install the model editing stuff that other people make, like reskins.

To install reskins just put the mpq into Program Files/World Of Warcraft/Data and run WoW with MEFix

But how can the server think that it's really the stairs? When you walk up the stairs, you're actually going up, and other people around you can see you in the air.

It doesn't, it think's your taking normal steps on something that could be there. If you imaging a black world with only the players, how would you know if there's not really stairs there? Well, the server can't know either. Pretty much everything done by the physics engine is client side. If you have ever seen an NPC that is in the air or something, they will be popping around. That is because the server sends a couple way points, and leaves it up to you to determine where and how exactly it will get there. Your game is still working 100% correctly as far as the physics engine goes, and the steps aren't huge such as trying to teleport to GM island. They're in normal, standard steps. Having the server calculate all this would cause way too much internet lag from the huge size and number of packets being sent, as well as a huge amount of server load to basically play all of the player's games. You can also teleport about 50 feet in the air with memory editing the Z axis, after a jump bigger than that, the server takes note of it, likely done by examining the average rate of movement by the player over a timestamp using basic trigonometry.

Completely off topic but one more post Verye and you have 1337 posts :P


Just thought I would throw that out there! ;]

The check is from clientside... You send a request to the server to summon itemid X ( X being a trap ( identified by a number - not by its size or height or anything else ) ) the server checks for cooldown and collision, then allows you / denys you from summoning itemid X.

After that its all clientside... WoW looks through the MPQs for X, and loads the itemid X. Wether X is a box, stairs, dark portal or a trap, this happens clientside, and would possibly create too much lag, for both the server and the player to check every thing loaded in the MPQ ( that's my theory )

Of course, blizzard could modify maps so it could check the Z coord every few X/Y coords... but they would have to make ALOT of exeptions for people using rocketboots / mount and slowfall, and any effect affecting your Z ( vertical ) coord.





TLDR; You check with the server to load your trap, the server checks for cooldown and sends you the answer. Your client loads the trap itemID, and does NOT check back with the server if it is indeed the object it needs to be.

It kind of sounds like a game flaw to me. I mean, if you went up to someone in WoW and told them "you can replace items with stairs and walk up them as if they're actually there," they'd probably shit their pants.

Aww I broke my 1337.

[Knomez]

you cant do that with normal weapons n stuff just like objects on the ground ^^

[BACKABACKA]

Yeah like if you campfire with stairs it will cary you up instead of burn you, cause that item is telling it to do something different than the item before. Other people wont see it because you have the edited files. They wont get the effect because they cant see it. If you cant see it, it wont affect you.

Not quite true.... If you make trash mobs into bunnies, they'll still rape you.

Yes... Rapist bunnies...

Some things which require scripts to run ( like mobs ) are still going to act normaly even after a model Edit.

Because your client loads the map files not the server. therefore, when you load a map file with a added file tree.m2, your client/computer loads the model, not the server.

In wow there are M2 (model files) who got animations, solid forms, particles etc. It doesn't matter if you swap a M2 with a particle or solid one, when swapped that M2 will "copy" the same attributes as that M2. For example, frost trap is not a solid M2, if you place it and you jump then nothing happens, you won't be on the "top" of the frost trap but you just stand again on the ground.

Now if you replace frost trap with a solid M2 like the stairs from AQ. The thing is, not only do you swap the appearance of it, you also swap the attributes of the M2. It's not that the server reads if there are actually stairs, no, it's that the client reads that there is stairs and making it possible to hop onto it.

Compare it with those lagg exploits. When you go in WSG, and pulling out the cable of your internet, but you are still walking, people that sees you actually see you as "lagging" but in fact, you are still running forward. Now, if you plug in the cable back again at the right time, you are just running normally, but for people that sees you as lagging, they think that you either teleport hacked or speed hacked.

The same thing with model editing. Everything that happens on your client side of wow also happens on the server side, the server doesn't need to read that there's actually a stair, it just visualize that what happens on your client side.

Hopefully this made you understand a bit more ^^
