Is (Random Integer between x and y) not really random or am I doing it wrong?

Hi, I'm Versae. I'm currently working a hero-survival type map (not very original, I know, although you'll see once it's finished :p) and I have a small question.

This is the trigger I currently have for all random mode. This trigger has no events as it is being activated by another trigger, but I don't think that should matter:
Trigger:
  • Hero Randomizer
    • Events
    • Conditions
    • Actions
      • Player Group - Pick every player in (All players matching (((Matching player) controller) Equal to User) and (((Matching player) slot status) Equal to Is playing))) and do (Actions)
        • Set Hero_Random = (Random Integer between 1 and 24)
        • Unit - Create 1 Hero[Hero_Random] for (Picked player) at (Center of Select Hero <gen>) facing Default building facing degrees

I have a few more actions in there but they are not relevant, as for example, one of them is just telling everyone that "(Picked player) has randomed (Last created unit)."

Here are the variables I have which are relevant to this question:
Hero_Random - An integer.
Hero[] - A unit-type array.

And to decide what each array number of Hero[] is equal to I have this:
Trigger:
  • Heroes Available
    • Events
      • Map Initialization
    • Conditions
    • Actions
      • Set Hero[1] = Paladin
      • Set Hero[2] = Demon Hunter
      • Set Hero[3] = Archmage
      • ...
      • Set Hero[24] = Pit Lord

And this list goes through 24 values, as I have 24 heroes available in my map in total.

However, here is my small problem:
Whenever I test this trigger by running the map and selecting all random mode, I always seem to be getting the same hero. I am always getting hero #19 on my list (Tinker), and I have run this test over 15 times now.
I have not tested whether every single player would get tinker, as I have only been testing alone so far, so I should probably do that, but for now there is still the issue as to why I am always getting the same hero.
Have I set up my trigger wrong?

no you set it up correct but what random number actual does is odd. some people think that it is based on current actions so try adding a wait in there before the random number

So you believe that just by adding a Wait action before the "Set Hero_Random" it will properly generate the random number?
I'll try that now, hopefully it works.

also make sure the Fixed Random Seed box isn't checked
which is in file -> preferences -> Test Map

Ok that did not work...

Here is my new trigger:
Trigger:
  • Hero Randomizer
    • Events
    • Conditions
    • Actions
      • Player Group - Pick every player in (All players matching (((Matching player) controller) Equal to User) and (((Matching player) slot status) Equal to Is playing))) and do (Actions)
        • Wait 0.00 seconds
        • Set Hero_Random = (Random Integer between 1 and 24)
        • Unit - Create 1 Hero[Hero_Random] for (Picked player) at (Center of Select Hero <gen>) facing Default building facing degrees


This time it did not even spawn the hero, in fact it did not do anything...

I then tried adding actions other than a "Wait" action, as I thought that maybe putting the Wait action was somehow breaking the trigger, and this time it did spawn a hero... But once again, the hero was always tinker...

EDIT: Fixed random seed! Wow, I didn't even know that option existed. I disabled it and the randomization worked perfectly. Thank you very much for your help :D. It wasn't like this was a game breaking issue, but it was bothering me quite a bit.

okay and a wait for 0.0 seconds will mess up a lot of stuff. if you use a wait at least us 0.01. for i myself just found that box the other day but my randoms were working fine. but your welcomed.

This. A computer is not capable of generating a random number. Instead, what it does is use several fixed seeds (values) and then uses an algorithm to pick a number, which mimicks a random selection. If you know the seed and the algorithm you can accurately guess the number the computer will generate. If "Fixed Random Seed" is checked, then the computer is always using the same seed and will therefore always pick the same number or sequence of numbers. A bit of a digression, but I hope that helps clarify what may be happening here.

Ah don't worry, I know what a seed is, I just didn't know that option existed ^.^

On a side-note, I don't feel like making a new thread for this, but I have 4 upgrades available for research in my map (let's just call them upgrades A, B, C and D), do you know how I could make it that when a player researches one of these upgrades all other upgrades become unavailable for research (for example, he researches upgrade A, upgrades B, C and D become unavailable)?

Didn't look at this for a very long time so there might be a better solution.

"Player - Set the max research level of YOUR_RESEARCH to 0 for Player 1 (Red)"

And make one for each of the upgrades unavailable for searching after the first one is picked.

    Crazy how much 3d printing has come in the last few years. Sad that it's not as easily modifiable though
  • Varine Varine:
    I bought an Ender 3 during the pandemic and tinkered with it all the time. Just bought a Sovol, not as easy. I'm trying to make it use a different nozzle because I have a fuck ton of Volcanos, and they use what is basically a modified volcano that is just a smidge longer, and almost every part on this thing needs to be redone to make it work
  • Varine Varine:
    Luckily I have a 3d printer for that, I guess. But it's ridiculous. The regular volcanos are 21mm, these Sovol versions are about 23.5mm
  • Varine Varine:
    So, 2.5mm longer. But the thing that measures the bed is about 1.5mm above the nozzle, so if I swap it with a volcano then I'm 1mm behind it. So cool, new bracket to swap that, but THEN the fan shroud to direct air at the part is ALSO going to be .5mm to low, and so I need to redo that, but by doing that it is a little bit off where it should be blowing and it's throwing it at the heating block instead of the part, and fuck man
  • Varine Varine:
    I didn't realize they designed this entire thing to NOT be modded. I would have just got a fucking Bambu if I knew that, the whole point was I could fuck with this. And no one else makes shit for Sovol so I have to go through them, and they have... interesting pricing models. So I have a new extruder altogether that I'm taking apart and going to just design a whole new one to use my nozzles. Dumb design.
  • Varine Varine:
    Can't just buy a new heatblock, you need to get a whole hotend - so block, heater cartridge, thermistor, heatbreak, and nozzle. And they put this fucking paste in there so I can't take the thermistor or cartridge out with any ease, that's 30 dollars. Or you can get the whole extrudor with the direct driver AND that heatblock for like 50, but you still can't get any of it to come apart
  • Varine Varine:
    Partsbuilt has individual parts I found but they're expensive. I think I can get bits swapped around and make this work with generic shit though
