This looks awesome but if there is one feature I would like to see is the ability to completely stop world generation after a certain point and be able to use the world partially generated.

Looks fantastic. Thank you once again for all your incredibly useful mods that I can no longer live without. :)


Can I ask why you'd want such a feature? Other than purely for testing purposes involving new biome spawns etc, I'd imagine doing this could really screw up the game.

If you have this installed, will it do the same for TerraCustom? (i.e. will TerraCustom detect this and therefore show the same ui to this?)
Yes, I tried it and it showed up in TerraCustom as normal. I may integrate it naturally in TerraCustom eventually, but either way, it works.

When I was testing some world gen code, I removed a few ranges from the task list using the ModifyWorldGen hook so I could generate basic worlds in a few seconds, you could try that. Also, I would also make items that would run the world gen code at the mouse cursor so I could test world gen code that way too.

BTW, the mod is open source on GitHub: https://github.com/JavidPack/WorldGenPreviewer

The code isn't too applicable to other uses in modding, but maybe the reflection bits can be a good example to someone.

If you are looking for a more normal example of UI within worldgen, maybe to give your user an option or something, below is a code example:

Code:
using Terraria.ModLoader;
using Terraria;
using Terraria.GameContent.Generation;
using System.Collections.Generic;
using Terraria.World.Generation;
using Microsoft.Xna.Framework;
using Microsoft.Xna.Framework.Graphics;
using Terraria.GameContent.UI.Elements;
using Terraria.UI;

namespace SkyDiveExperiment
{
    public class SkyDiveExperiment : Mod
    {
        public SkyDiveExperiment()
        {
            Properties = new ModProperties()
            {
                Autoload = true, // We need Autoload to be true so our ModWorld class below will be loaded.
            };
        }
    }

    internal class InterruptModWorld : ModWorld
    {
        internal static bool continueWorldGen = false;
        internal static bool skydive;

        public override void PostWorldGen()
        {
            Main.MenuUI.SetState(new ExampleUI());
            while (true)
            {
                if (continueWorldGen)
                {
                    if (skydive)
                    {
                        Main.spawnTileY = 100; // Do things based on choice
                    }
                    Main.MenuUI.GoBack();
                    continueWorldGen = false; // reset for next world gen
                    break;
                }
            }
        }
    }

    class ExampleUI : UIState
    {
        public UIPanel coinCounterPanel;

        {

            coinCounterPanel.Width.Set(300f, 0f);
            coinCounterPanel.Height.Set(100f, 0f);
            coinCounterPanel.BackgroundColor = new Color(73, 94, 171);

            UITextPanel text = new UITextPanel("Would you like to go Sky diving?");
            text.HAlign = 0.5f;
            text.Top.Set(5f, 0f);
            coinCounterPanel.Append(text);

            _buttonLabel = new UIText("", 1f, false);

            coinCounterPanel.Append(_buttonLabel);

            Texture2D buttonPlayTexture = ModLoader.GetTexture("Terraria/UI/ButtonPlay");
            UIImageButton playButton = new UIImageButton(buttonPlayTexture);
            playButton.Width.Set(22, 0f);
            playButton.Height.Set(22, 0f);
            playButton.VAlign = .8f;
            playButton.HAlign = .25f;
            playButton.OnClick += new MouseEvent(PlayButtonClicked);
            playButton.OnMouseOver += new UIElement.MouseEvent(PlayMouseOver);
            playButton.OnMouseOut += new UIElement.MouseEvent(ButtonMouseOut);
            coinCounterPanel.Append(playButton);

            Texture2D buttonDeleteTexture = ModLoader.GetTexture("Terraria/UI/ButtonDelete");
            UIImageButton closeButton = new UIImageButton(buttonDeleteTexture);
            closeButton.Width.Set(22, 0f);

            closeButton.HAlign = .75f;

            base.Append(coinCounterPanel);
        }

        private void PlayButtonClicked(UIMouseEvent evt, UIElement listeningElement)
        {
            Main.PlaySound(10, -1, -1, 1);
            InterruptModWorld.skydive = true;
            InterruptModWorld.continueWorldGen = true;
        }

        private void CloseButtonClicked(UIMouseEvent evt, UIElement listeningElement)
        {
            Main.PlaySound(10, -1, -1, 1);
            InterruptModWorld.skydive = false;
            InterruptModWorld.continueWorldGen = true;
        }

        private void PlayMouseOver(UIMouseEvent evt, UIElement listeningElement)
        {
            this._buttonLabel.SetText("YEAH!");
        }

        private void DeleteMouseOver(UIMouseEvent evt, UIElement listeningElement)
        {
            this._buttonLabel.SetText("No way!");
        }

        private void ButtonMouseOut(UIMouseEvent evt, UIElement listeningElement)
        {
            this._buttonLabel.SetText("");
        }
    }
}
It provides an option to "skydive" during worldgen. All that means is you start in the air and die. It isn't useful, but hopefully this code example is simple enough to show how it works.
