What are you trying to achieve and are there any error in debugscript 3?

[Swagy]

Well, this is an inventory system, so If you drop the item, it will create a pickup and when you take the pickup it gives +1 that item, 

 

the error is: Expected element at argument 2, got boolean 

 

for addEventHandler ("onClientPickupHit", pickUp, function)

[3aGl3]

I think you want to move the line

addEventHandler ("onClientPickupHit", pickUp, takeObject)

into the dropItem function.

[Swagy]

It didn't work, I just want to use the pickups later on.

 

I mean, add a new function but use those pickups in the function, I want to make the pickups as global variables work in the eventHandler..

[Swagy]

Any help please ? I need to know how to fix this please.
