So i've added a new block to my mod. So far all i've done is added to the game. i havn't given it any crafting recipes or made it part of any. When i start minecraft up to test everything via eclipse my minecraft shows a crash report. i know it has to do with the new item i've added because of this line (java.lang.ArrayIndexOutOfBoundsException: 5821) but i can't seem to figure out what exactly is causing this. My coding seems to be perfect. No errors where given to me by eclipse so please help. This is my crash report :

Your block ID is too high, max is something like 4095 (as array has 4096 elements but we count from 0)

What's that block ID for you block? Try making it 300.

judging form the error his blockId is 5821

Your block ID is too high, max is something like 4095 (as array has 4096 elements but we count from 0)

Strange because some of my other items ids are in the 4800s and they havn't crashed the server. But yes that was the problem. the id was to high for this block. Thanks for the help!

items ids are in the 4800s

 

Items != blocks.

 

ITEM IDs can go as high as 31999.  BLOCK IDs can go up to 4095.
