Help with Array and Inventory

I want to make a simple inventory system:

• 3 inventory slots, each slot can have one item.
• if player used item, that slot will be empty.
• next time player acquire a new item, the item will be put into the first empty slot.

I know array will do the job, but it would be so helpful if someone can give me a hint:)

Go check out the Arrays for beginners tutorial , making this wouldn't be too hard , you just need to check if there is a 0 in the array and remplace the zero by the ID of an item in a for every elements loop ...

I'll make you an example when I get home

Thanks Whiteclaws! Won't the loop replace every cell of 0? but I'm looking forward to your example:)

There's where a variable enters , the loop will only be triggered if a variable is equal to 0 , and the variable will turn 1 when the item is added successfully !

Here We Go !

P.S: That's the first time I do something like this :) . Arrays , I'm starting to love-em !

Wouldn't a simple "Trigger once while true" prevent it from changing every instance?

Well , Yes , but I just wanted to show that the usage of variable with arrays is possible

(Screw this , I completely forgot the "Trigger once while true" :P )

Thanks for the example and hint!
