[Tut] How to use Update.mrs

[wtfhacker]

Almost all poeple really don't know how to.

Open new folder called Update1 or update2, and etc,
Put the mrs to be updated INSIDE the Updatex.mrs, Ex': System / model / SFX and etc.

And compile it and we done.
Simple Tut, easy way to update, low weight.

Thank me if i helped .

If you want to make a tutorial about such an easy thing, put some effort into it.

[aishkterry1]

maybe some photos would be better :D

[Phoenix]

You aren't supposed to put the mrs to be updated INSIDE the Updatex.mrs. You're supposed to place a unpacked folder of the mrs to be updated inside the Update mrs. Please get your facts straight before making tut's. Delete this tut or edit it.

phoenix_147 - I know but my english is not that good.
Btw read the top, i said not all poeple know this.

[Project]

I don't understand what this is for, the update.mrs.

I've seen it, but never knew what it was actually for.

Nor do I understand what you're trying to explain.

[wtfhacker]

Because, think: Model weights 40mb right ? and to update it takes about 10 minutes, just think it.
And you use Updatex.mrs to update low weight files.

[tuantep]

4 a simple exam:

+ You create new folder Update1. Open it and create new folder system open it and copy your system.xml into it. Open system.xml and change the IP is incorrect.

+ Pack Update1 folder -> Update1.mrs and put into your GunZ Folder.

+ Run GunZ.exe and you can see the changing.

+ Delete Update1.mrs and Run Back... :D

Does work, check your code of your runable.
Its worth to note that the files within updatex have to be NEWER than the files that replace the old files.
Otherwise gunz wont load them.

he must have packed files inside update.mrs also lol..

[HellSniper]

he must have packed files inside update.mrs also lol..

Likely, or actualy made a updatex.mrs.
Who knows.

[megol]

Try all that but still does not work, that code should look aver if wrong, in the "cml".
