Drop rates, Spawn rates, calculation

WhySoCREATIVE

Hello, anyone know some mathematical solutions on how to create spawn rates? I want to randomly spawn an actor maybe at 10% chance and user is able to upgrade this change to 20% 30% and so on...

Make an integer attribute called game.spawnChance. Then set up your rules as follows:

Change attribute game.spawnChance to random(1,10)
When attribute game.spawnChance < 2
     [spawn an actor... this is a 10% chance]

or, When attribute game.spawnChance < 3
     [spawn an actor... this is a 20% chance]

etc.

Click the green actor to add 10% chance of white actor spawning the orange when you click it.

Yes, so you'd want a self.spawnChance for each actor in that case. And actually, the attribute you want to change would be self.probability (for lack of a better name). That's the 2 or 3 in the rule I posted above. So more like this:

Initially, set self.probability to 2.

Change attribute self.spawnChance to random(1,10)
When attribute game.spawnChance < self.probability
     [spawn an actor... this is a 10% chance]

Then, later change self.probability to 3, which increases the chance to 20%.

Thanks so much guys! @tatiang I assume I will need multiple game.spawnChance attributes for each actor then If they can be individually upgraded to higher chance.
