[1.11.2] hide the other hand/item while the mainhand is in use

[perromercenary00]

good days

some time ago i made the same question and the answer means to  mess whith an event in the client side,

But that method has its down side for why i end not using it 

 

 

now im thinking in create and item whith a transparent texture, give this item a capability of store an slot and giveit  a timer afther what it will disapear from inventory and restore the original item to he slot 

 

let say i have the bow in the offhand slot the [40]  and have the arrow  in the main hand slot[2]

so i made the code in the bow to wen it reach onitemUse()  tick = 1;

its call the transparent item,

via capability the transparent item gonna store the mainhand stack from slot[2] and set itself in that slots[2] whith a timer of 20ticks afther that 

the transparent item set again the arrowstack in the slot[2] and delete ifself, if after 20ticks the bow is still thigtheng  it repets the operations until shoot the arrow 

 

well this solution seem to me to complicated but its something
