tomkail / PresetImportPerFolder.cs

	using System.IO;
	using UnityEditor;
	using UnityEditor.Presets;
	using System.Linq;

	// This script automatically applies Presets to assets when they are imported into a folder containing a Preset.
	// It also adds any labels on the Preset file to the asset.
	public class PresetImportPerFolder : AssetPostprocessor {
	void OnPreprocessAsset() {
	// Make sure we are applying presets the first time an asset is imported.

tomkail / GetLocalToAnchoredPositionOffset.cs

Created December 20, 2022 14:47

Converts between localPosition and anchoredPosition for a RectTransform.

	// Add this to convert a local position to an anchored position
	public static Vector2 GetLocalToAnchoredPositionOffset(this RectTransform rectTransform) {
	var parentRT = (RectTransform) rectTransform.parent;
	var pivotAnchor = new Vector2(Mathf.LerpUnclamped(rectTransform.anchorMin.x, rectTransform.anchorMax.x, rectTransform.pivot.x), Mathf.LerpUnclamped(rectTransform.anchorMin.y, rectTransform.anchorMax.y, rectTransform.pivot.y));
	return -parentRT.rect.size * (pivotAnchor - parentRT.pivot);

	// Music,
	// Narration,
	// }

tomkail / Better TextMeshPro GetRenderedValues

Last active June 14, 2024 10:48

Better GetRenderedValues for TextMeshPro that doesn't return NaN/other invalid values and allows you to test with custom text

	// Applying float.MaxValue to a rectTransform can cause crashes (not sure why) so we just use a very big number instead.
	const float veryLargeNumber = 10000000;

	// Gets the tightest bounds for the text by updating the text and using GetRenderedValues
	// Note this uses sizeDelta for sizing so won't work when using anchors.
	// This is wayyyy more reliable than the actual GetRenderedValues because it won't return stupid values, as GetRenderedValues is prone to doing.
	public static Vector2 GetRenderedValues (this TMP_Text textComponent, string text, float maxWidth = veryLargeNumber, float maxHeight = veryLargeNumber, bool onlyVisibleCharacters = true) {
	if(string.IsNullOrEmpty(text)) return Vector2.zero;
	// Setting RT size to Infinity can lead to weird results, so we use a very large number instead.
	if(maxWidth > veryLargeNumber) maxWidth = veryLargeNumber;

tomkail / ColorDescriptor.cs
