So I got the I replaced the method for ItemStack#onItemUse() but, it appears that it is refusing to load the blockpos class or something. 

New Method:

Why do I need asm to fire a forge event: because forge doesn't fire a block place event for client side and my mod silkspawners needs it but, in the past I was replacing the block the improper way rather then patching a class to fire for every block placement. So no ASM isn't an option since said forge event doesn't exist for the client side so I made one.

I don't understand the error since the class blockpos is already in the code to begin with proper imports. I tried manually loading the class before doing anything else both the ob and deob class for ob and it didn't work same error

Why do you need a client side block place event?

for client side particles and tile entity render sync so it doesn't render wrong for the first couple ticks. Also it's a nice event to have that I want implemented

packets are too slow already tried sync needs to happen when the client thinks it should

If I switched my asm to ItemBlock class it would work since BlockPos by then is loaded but, forge had their method there for a reason because then modders could accidentally override forge and block place event would never fire. So they do it on the itemstack level and that's also what I would like to do.

Then submit the event to forge on github.

You could just send a packet updating the client.

packets could take 100ms+ over the network that's the equivalent to 2-5 ticks event needs to happen exactly when the client does their method. No delay is acceptable or it renders wrong.

for example in silkspawners placing a spawner with your idea would resault in 0.2-0.5+seconds of rendering pig I need it to render creeper instantly if it's a creeper. Plus this is what vanilla already does and I am trying to avoid it need a client sync to happen instantly when it has the data which is the same tick it places it

What I need to know is why it can't find the block pos class? the code worked for replacing every single other method except for the itemstack class

After looking at your silkspawners mod on github it turns out you have your own mob spawner block that can modify what you want on the client in the onItemUse method.

cannot as it doesn't work with modded blocks. my mod supports any block with the instanceof tile entity spawner on server side I am trying to fix client sync here.

I can't do that since the asm is throwing an error of blockpos not found during runtime. I need to know what I am doing wrong?

You're doing it for your block, not others mods.

Locked.

JRed you are consistently coming around asking for help with your fucking coremod that I'm fairly sure every member of staff has asked you to stop using, yet you insist on hacking the shit out of everything because you think you know better yet you refuse to prove that your way is better by contributing to Forge directly.

I will say this again, if you are having trouble with making a coremod maybe you shouldn't be hacking the shit out of other people's code.
