Is there any way I can tell if a player is on multiplayer when he(or she) joins a world? Basically I want to run some code if the player is going on multiplayer but not on single player.

So u want them to give different blocks?

Thank You Those weird methods were copied from: Minecraft TileEntitys and other open source mod TileEntitys, i removed all the ones that i didnt know what they were for and it worked . It turns out leaving things when im not sure what they are isnt always the best solution. Your name: "FlameAtronach93" will be on the credits list when this mod is released! My new TileEntityPortalSpawner code (For reference if any one else has this problem):

First of all, thanks for replying I did notice that, i am using eclipse and i thought it should warn me too. Here is the TileEntityPortalSpawner code i cant see a duplicate method but maybe i'm missing something(I have been looking at code for the past 2 days) I'm very messy when i code

I had the same error i fixed it by changing the "public ItemStack transferStackInSlot" method to: It worked for me, it stopped the game from crashing.

I have been making a mc forge mod for a while now, it works fine on mcp, and i recompiled and re-obfuscated it and tried to load it onto minecraft(Clean .minecraft with only forge installed). I get this error: I did some research (for like 2 hours) and found no solution. A lot of forum posts say to make sure that the classes for a mod are in the right place in the .zip, well mine ARE. Please HELP! :'( If the error is in the code then i can post that!
