Hey im trying to place a different block depending on the different nbt's but it crashes.

Method:

 

public boolean onItemUse(ItemStack itemstack, EntityPlayer player, World world, BlockPos pos, EnumFacing side, float hitX, float hitY, float hitZ) {

if (player.isSneaking()) {

itemstack.getTagCompound().setString("effect", "No effect");

} else if (player.canPlayerEdit(pos.up(), side, itemstack)) {

 

if (itemstack.getTagCompound().getString("effect") == "Toxic") {

world.setBlockState(pos.up(+1), BioWarfareBlocks.block_BacteriaTestToxic.getDefaultState(), 3);

 

--itemstack.stackSize;

return true;

}

if (itemstack.getTagCompound().getString("effect") == "InvertedVision") {

world.setBlockState(pos.up(+1), BioWarfareBlocks.block_BacteriaTestInvertedVision.getDefaultState(), 3);

 

--itemstack.stackSize;

return true;

}

if (itemstack.getTagCompound().getString("effect") == "BlurredVision") {

world.setBlockState(pos.up(+1), BioWarfareBlocks.block_BacteriaTestBlurredVision.getDefaultState(), 3);

 

--itemstack.stackSize;

return true;

}

if (itemstack.getTagCompound().getString("effect") == "XPDrain") {

world.setBlockState(pos.up(+1), BioWarfareBlocks.block_BacteriaTestXPDrain.getDefaultState(), 3);

 

--itemstack.stackSize;

return true;

}

if (itemstack.getTagCompound().getString("effect") == "Rooted") {

world.setBlockState(pos.up(+1), BioWarfareBlocks.block_BacteriaTestRooted.getDefaultState(), 3);

 

--itemstack.stackSize;

return true;

}

if (itemstack.getTagCompound().getString("effect") == "Diarrhea") {

world.setBlockState(pos.up(+1), BioWarfareBlocks.block_BacteriaTestDiarrhea.getDefaultState(), 3);

 

--itemstack.stackSize;

return true;

}

 

}

return false;

 

}

getString("effect") == "Toxic"

That is not how you compare strings.

 

== is comprasion of 2 objects.

 

you need to use string.equals()

 

EDIT

Also - after decrementing stack's size you need to MANUALLY check if its == 0 and set stack to null (from player.inventory level).

1.7.10 is no longer supported by forge, you are on your own.
