Are MCreator mods Server-compatible?
Tue, 06/13/2017 - 20:27

I have a guy trying to install my Hodge-Podge Mod II on a server, but it is not working. I do not know whether or not it is even possible to run a MCreator mod on a server, and I do not have the capability to test this myself.

Does anyone know a solution to this? Here is the guy's error log:

Well, MCreator is +- server
Tue, 06/13/2017 - 20:55

Well, MCreator is +- server compatible - unless you start using events. Their code was not fixed at all. Simply what the error says it that you are trying access client-side class from server-side code. If I am right, MCreator does this mistake especially at a thing like a block interaction. Fixing it is quite easy. You make the code that calls the class just client-side (if it is something related to rendering, particles,...) or you must use some server/both sides alternative to the specific class.

@#1 Could I get an example of each?

1-make the code that calls the class just client-side (if it is something related to rendering, particles,...)

2- you must use some server/both sides alternative to the specific class.

For stuff that is supposed to
Wed, 06/14/2017 - 21:23

For stuff that is supposed to be called just from client put @SideOnly(Side.CLIENT) annotation right before the method, class,...
In case that the code actually is supposed to be called by both/just server it is a bit complicated and depends on your actual code - simply,there are some classes that usses the annonation that I mentioned above. These are ussualy relicts from ages , when minecraft was complytly client/server divided. There you need use a class (or if the annonation applies jsut for a method) that does nto have it. So you want use instead of EntityPlayerSP a EntityPlayer or EntityPlayerMP.

I know this is an old thread…
Wed, 07/04/2018 - 13:15

I know this is an old thread, but I'm going to have to ask "where???" as well.  Here's the relevant line in my crash report:

 

Caused by: java.lang.NoClassDefFoundError: net/minecraft/client/entity/EntityPlayerSP
	at mod.mcreator.mcreator_uraniumOre.<clinit>(mcreator_uraniumOre.java:66)

 

OK, I got it, EntityPlayerSP is deprecated and should be changed.  So, I go into the code at line 66 and this is what I find:

 

block = (BlockUraniumOre) (new BlockUraniumOre().setHardness(2.0F).setResistance(10.0F).setLightLevel(0.0F).setUnlocalizedName("uraniumore").setLightOpacity(0).setCreativeTab(CreativeTabs.BUILDING_BLOCKS));

 

????? O.o  Nowhere on line 66 in mcreator_uraniumOre is "EntityPlayerSP" mentioned.  It's not even in the mod element at all.  I'm guessing it's somehow getting called through a different method, but damned if I can figure out which one.

I have a theory as to what could be going on, though, since you mentioned that "EntityPlayerSP" is a throwback to the old days as to how Minecraft handled the differences between being a client and a server.  For sh*ts and giggles, I re-created this mod element in a brand-new mod (since *this* mod element is part of an older mod that I got from an imported .mcr file from a previous version of MCreator).  Running *that* brand-new mod from a brand-new workspace in a server environment resulted in *no* crashes.

So, I'm wondering if there's something, somewhere, in the workspace or another mod element or *something* that's causing the crash for EntityPlayerSP, but *only* for workspaces that have been imported from a previous version of MCreator.  I'm probably wrong, I'm sure I'll get the same crash as I fiddle around with the new workspace...but if I'm *right*, then I'm still confused as to where "EntityPlayerSP" is hiding.  But, at least, while we wait for the MCreator dev team to fix this problem in a later version, people can just simply re-build their mod in a clean workspace.  I know that sucks for those of us with *huge* mods (myself included), but it's better than nothing.

Oh, nevermind, I just figured it out and what/where you meant.  Duh.

 

Thanks!
