Small tool for working with tilemap layers (inside scene view)

mgear · June 30, 2016, 2:02pm

Started on small editorscript to make using layers easier…

currently just 1 feature:

Swap tilemap layer with PageUp/PageDown keys

*note: clicking the layer buttons with mouse doesn’t do anything yet

source:

UnityCommunity/UnityLibrary/blob/master/Assets/Scripts/2D/Tilemaps/Editor/TilemapLayerHelper.cs

using UnityEngine;
using UnityEditor;

#if UNITY_2017_2_OR_NEWER 
using UnityEngine.Tilemaps;

//Requires Unity 2017.2 or newer

// TilemapLayerHelper
// Use PageDown/PageUp to select between tilemap layers
// First assign tileRoot into the editorwindow field and hit GetTileMaps button
// Set scene view zoom: Press G to toggle between: Framed, PixelPerfect, HalfWay

public enum FrameMode
{
    Framed,
    PixelPerfect,
    HalfWay
}

Good work. Keep this stuff coming.

Added:

Separate hierarchy helper script : UnityLibrary/Assets/Scripts/2D/Tilemaps/TileMapHierarchyHelper.cs at master · UnityCommunity/UnityLibrary · GitHub (get icons from here)
Can arrange layer order with those small arrows (because sometimes its difficult when you try to drag&drop arrange gameobjects, they get accidentally parented etc…)
Displays custom icon for tilemap gameobjects (green if gameobject is active)

Just for testing so far, not sure if it needs icon, and still thinking if/how locking a layer would do…

You shoud update the original post too, if not it seems like it is still the first version (at first glance)
Oh, and nice feature !

This is great, I’m surprised they haven’t integrated this into their own build! Wow.

Updated the source in original post link^

Fixed: Keyboards event were all eaten/used, now only for those keys that are used
Added: Press G to toggle between Framed, PixelPerfectZoom, HalfWayZoom (at mouse position) *currently pixelPerUnity ratio is set fixed to 16 (would need to take that from tilemap sprites)

Ill later change that Framed, into “Fit to view” instead…

Pressing G button to have better framing/zoom:
