SnapBuilder is the snap-to-grid mod for Subnautica & Subnautica: Below Zero you've been dreaming of!

• Snap-to-grid enabled for all items! (Doesn't apply to rooms as they already snap together)
• When aiming at a wall or the side of an item, will automatically snap the item into position!
• Automatically upgrades inaccurate hitboxes so that items can properly snap to them! (Mostly only applies to Subnautica: Below Zero)
• The range for building can be extended and customised! (On the legacy branch of Subnautica, this only applies to items, not rooms)
• All keybinds and parameters can be tweaked in-game with Configuration Manager! (Simply press F5 to open the configuration window)
• Fully compatible with the QMods and the legacy branch of Subnautica!
• Fully compatible with Decorations Mod!

• The relevant BepInEx pack for your game:
  • BepInEx pack for Subnautica
  • BepInEx pack for Subnautica: Below Zero

• Vortex Mod Manager (Windows only) - Makes installing mods a breeze.

Most issues are resolved by carefully re-reading the installation instructions or stickies at the top of the Posts tab on the relevant Nexus Mods page (Subnautica, Below Zero), but if you have stumbled on a bug, please file a bug report on the Bugs tab (Subnautica, Below Zero) with as much information as possible to help me find the cause and get it squashed in an update.

By default, most items added to the game by other mods should work just fine with SnapBuilder assuming they also work fine in-game. For the edge cases where they do not and SnapBuilder does not understand which way to rotate your items by default, it is easy to make your items compatible without a dependency on SnapBuilder.

On your prefab's model GameObject, simply add a child GameObject named SnapBuilder. Whatever you set the localRotation and localPosition of this GameObject to, SnapBuilder will treat these as the default transformations for the item.

The GameObject named SnapBuilder must be the direct child of the GameObject located at Builder.ghostModel when the user is interacting with the Habitat Builder.

For example:

        public override GameObject GetGameObject()
        {
            GameObject prefab = ... // code to load your prefab goes here

            // Get model
            GameObject model = prefab.FindChild("MY_MODEL'S_TRANSFORM");

            // help snapbuilder understand the model
            var snapBuilder = new GameObject("SnapBuilder");
            snapBuilder.transform.SetParent(model.transform, false);
            snapBuilder.transform.localEulerAngles = new Vector3(-90, -90, 0);

            // do other stuff...
        }

Turboboost your Subnautica loading times!
