I made a block called Mixer. I tried to make a recipe where you need items that the mod also add but when I put the items in crafting table in the right order nothing happens. Here the code of the recipe:

ItemStack stackRB = new ItemStack(Blocks.redstone_block);

ItemStack stackt = new ItemStack(this.tryptonidCry);

ItemStack stackib = new ItemStack(Blocks.iron_block);

ItemStack stackb = new ItemStack(this.brantinIngot);

ItemStack stackOp = new ItemStack(this.mixEl);

GameRegistry.addShapedRecipe(stackOp, "ibi", "rtr", "ibi", 'i', stackib, 'b', stackb, 't', stackt, 'r', stackRB);

 

Whats the probleme?!

this is what i use for my recipes, it works for me so it should for you.

 

GameRegistry.addRecipe(new ItemStack(GrindStoneIdle), "srs", "sgs", "pbp",
	        'r', Items.redstone, 'g', ItemHandler.GrindStone , 's', Blocks.stone, 'p', Blocks.planks, 'b', Items.bucket);

i think its because you are creating new instances of your itemstacks

 

No.

 

OP: Are you sure your recipe registration code is actually getting called? From where are you calling it? Show more of your code.

i think its because you register the recipes before you register the blocks/items. that is the only explenation i could think off

This is almost certainly the case.

That was right but now it crashes null point exception

Those are easy to solve without help and impossible to solve without both the code and the crash report.

Since all of my recipes are registered in my init method, not preinit, my guess is that preinit is too early in some cases. Of course, it would help if you told us what pointer was null at what line of what file.
