One-time items/collectibles from breakable objects - How to best implement

[Keith_1357]

You could put the object names in an array similar to this example. You pick a random number based on the number of items in the array, create an object from that element and then remove it from the array.

[Solved] Creating objects from a group to appear only once in the entire game in a random order

You can put the object names into an array either through the variable editor or with events as in this example. You can then create an object using a random number to pick a name from the array. You then delete the element from the array and repeat until the array has zero children. (This uses 4 sprites named “NewSprite0” through “NewSprite3”) [image]

Now, in your case you could add the randomly picked object’s name to another array and then every say 5 minutes remove an element form that array using the same technique and then add it back to the main list.

Another approach might be to add some bias to the picking of objects. Maybe have 3 groups; common, medium and rare. You could then pick a random number from say 1 to 100. If the number is from 1 to 70 then pick a random common item. If it’s 71 to 90 pick a meduim item. If it’s between 91 to 100 choose a rare item.
