Spawning followers

[Killerstrike1234]

How would I spawn a follower as a trait or an ability for a custom mod

You can use one of the SpawnerMain.SpawnAgent methods to spawn a follower.

As a custom ability it would look kind of like this:

public class FollowerSpawn : CustomAbility
{
    [RLSetup]
    public static void Setup()
    {
        RogueLibs.CreateCustomAbility<FollowerSpawn>()
            .WithName(new CustomNameInfo("Follower Spawn"))
            .WithDescription(new CustomNameInfo("A special ability that spawns followers."))
            .WithSprite(Properties.Resources.MySprite)
            .WithUnlock(new AbilityUnlock());
    }

    public override void OnAdded() { }

    public override void OnPressed()
    {
        if (!Owner.CanHaveMoreFollowers(true))
            return; // the user can't have any more followers

        // get the user's position
        Vector2 userPos = Owner.tr.position;
        // get a random direction
        Vector2 randomDir = Random.insideUnitCircle.normalized;

        Vector2 followerPos = userPos + randomDir * 0.64f; // 0.64f = 1 floor tile

        // spawn a follower
        // (we'll reuse the Friend Phone's code in here, see ItemFunctions.UseItem(...))
        Agent follower = gc.spawnerMain.SpawnAgent(followerPos, Owner, "Bouncer", "FriendPhone", Owner);
    }
}

[Warning:RogueLibsCore] Custom item RogueLibsCore.Test.JumpScare doesn't set the Item.itemType field!

[Chasmical]

Items need to have their itemType set. Look at InvItem.SetupDetails() in the game's assembly for more info.
There's a useful helper class in RogueLibs called ItemTypes. It has all of the available item types declared as constant strings.

but how do I fix this if its just an ability not an item

[Chasmical]

Huh.. I thought I disabled that check for custom abilities. Then just ignore that warning.

im not sure if its the reason but it appears to stop the next level from loading
