[solved][1.19.2] events detecs when one of mi custome blocks is in the hand of the player

[perromercenary00]

uhh im doing something complicated 

i made some panels blocks of various materials and glass also its just 1/4 of a full block and can have 6 directions that works nice but

 sometimes is a little hard to set the panel in the exact place i want it to be

 

too fix that i made an entity based on  abstract_arrow called "aligner_entity" for now is just a white gray texture.

this entity binds to the player and every 5 ticks detecs what the player looking at and updates its position|rotation to mach where a panel_block  would be placed if any  

the entity works nice and all 

#######################################################################

 

now i need to spawn the entity and bind it to the player any time the player hold one of mi blocks in its hand and also kill/discard the entity when player change to someting else 

soo i doo the event thing

		            }
		        }
		    }				
			
		}				
			

the LivingEquipmentChangeEvent event trigers everytime the player select an item in the hotbar 
the comented code its just experiments i been doing
 

sorry is hard to comunicate complex ideas in a non native languague 
the "if (itemstack.getItem() == BlockInit.MANHOLE_PANEL.get().asItem())"   works to detect mi block but i have like 120 it would be not resources wise to make a list and compare against all 120 blocks everytime the user select a diferent item in the hotbar 

   all mi blocks are made from 3 main classes 
panel.class

puerta.class

trampilla.class       //this one is instance of puerta soo it dont mathers   

 

if i try to made an 

"if (itemstack.getItem() instanceof panel && !warudo.isClientSide) " //

it says 

"incompatible conditional operand types item and panel" 

sounds logic coze one is an item object and the other is a block class 

 

#####################################

ya i need is to know if the item form the itemstack the LivingEquipmentChangeEvent gives me was made from the panel block class 

without having to compare to each all of mi blocks 

 

 

thanks for your time
