Minecraft/DataPacks Detect when an entity is within a range from a certain block

So my current solution is mildly ugly and horrendous but at least it works most of the time.
I've been working with predicates more and realized that I could use the "Alternative" predicate as an "or" statement between other predicates and stitched together a Frankenstein of location checks so that when a skeleton/zombie/spider first spawns it checks the blocks around it to see if there is a spawner. Sometimes this fails (probably cuz it does almost 150 location checks) but it's the best "working" solution I have so far. I'll probably still keep looking though because I don't know how bad this could affect world/server performance.


(the code seems to get compressed weird when I paste it in here but it's mostly just to show how horrible this solution seems to me)

The Monster predicate checks :/ (this is 1/3 of it)

I appreciate the idea but at the same time the root of my problem as far as I can tell is detecting where a a certain block- in this case a mob spawner is. So far in my pack the spawners are not truly disabled- I don't know a way to truly disable mob spawning I just counteract it by using scoreboards and sending unwanted mobs to the void. That being said if a mob exists for more than two ticks or accumulates a score of 2 or more they don't get void yeeted.

Anyways, the fact that the spawners are not truly disabled gave me a window of hope that maybe I could do something in the one tick that the mobs get to exist before they get sent to the recycle bin.

and while spawndata only sets one spawn, I could maybe do something with spawn potential as HoboMaggot pointed out, but in looking at spawn potential modification I didn't see an easy way to give them custom scores. I did notice that with spawners they can be assigned teams though so I might look into that.

Answer: Once they spawn they can walk around freely.

my problem currently is detecting where in the world mob spawners are. Without that summoning mobs with commands seems a bit off.

I tp them into the void, but if they spawn outside the area and exist longer than two ticks they get a score higher than the minimum that lets them wander into the area. my thinking for a workaround would be to add to their scores even more if they spawned near a mob spawner- that way they wouldn't get void yeeted.

hmmm... maybe... I hadn't thought of that but what I need has to be preformed in one tick so that it can prevent the mobs from being removed in time. If I understand right recasting isn't instant and would take a lot of set up and multiple ticks.

The json program I was using was formatting stuff wrong, so while it looked good it actually needed to be a little different:

The working code:

"criteria": {
  "requirement": {
    "trigger": "minecraft:inventory_changed",
     "conditions": {
       "items": [
        {
        "items": [
         "minecraft:oak_planks"
        ],
        "nbt": "{display:{Name:'{\"text\":\"A\"}'}}"
       }
      ]
    }
  }
}
