Probability Advice

[Karzama]

Hi all,

Hit an issue in my map and I can't think of a way around that I'm happy with...

So my issue is how enemies fought are randomized, it's based on the current round and the difficulty. So later rounds harder enemies spawn.

However I also made each unit have different "tiers" that can spawn based on difficulty & round again.

So let's make an example...

Unit 1 has 50 spawn rate
Unit 2 has 200 spawn rate

If the round & difficulty get too high then Unit 2 becomes more common, but the higher tiered versions of Unit 1 are actually stronger, which then makes the game easier...

Hope that makes sense..? Any ideas??

It seems you have two dimensions that are changing here: the relative spawn rates of creeps and their tiers. To simplify things, you should get rid of one of them.

So, either keep spawn rates for each type of unit the same throughout the game and update their tiers only, or you can get rid of the concept of tiers and just have a large pool of unit types where each individual type has a different spawn rate based on the difficulty and round number (weak enemies would eventually have a spawn rate of 0 and strong ones would start at 0).

Thanks for the suggestion, I've just been trying to create a different method to get to each spawns. By running the spawns in tier order, in my head it could work. The idea of Tiers was that you would fight the same unit just a stronger version of it, with each tier having a really high spawn rate to match their stat bonuses (in some sense). Have posted the 2 triggers to compare new to old, what do you think?
