Check if item exists ?

[maxBot90 0]

Hello, I just started working on wine of zammy grab script , but my problem is unless I hard code some timers I cant get it to work flawless and my issue is I cant do ground items check as it always returns null for me and cause crashes using many different methods , like using exist() function or any way I can detect it to spawn other than hard coding . So I'd like to see some snippets to perfectly detect Item if found so I can use it on different conditions , also I have done a cow script which loot cowhides and I based it on distance of cowhide only which seems sucks but thats the only issure bellow is some snippet I tried and it always returns null or cause crash.

(Contains many stuff as I am trying many different things so dont judge 😜
