trying to modify spear spawn chance through code | Rain World | Page 1

I want to modify the spawn chance of a rock being replaced with a spear, but cannot find the code responsible for randomly spawning items at the beginning of the cycle. The closest I could find is this:

    {
        get
        {
            if (this.rndItmDns != null)
            {
                return this.rndItmDns.Value;
            }
            return this.parent.RandomItemDensity;
        }
        set
        {
            this.rndItmDns = new float?(value);
        }
    }```
inside the RoomSettings class. I think this is enough information to help.

Basically, does anyone know where to find the function or whatever responsible for randomly spawning items at cycle start?
