Description

Do you like TextMeshPro? I’m lovin’ it:)

As you know, TextMeshPro, the ultimate text solution, is one of the greatest assets in Unity.
It is more beautiful than the standard TextMesh and Text, it is highly functional and free.

One of the big mystery of TextMeshPro is that "typical mesh effects (vertex effects) for uGUI can not be used for TextMeshPro".
Since TextMeshPro does not call IMeshModifier interface, TextMeshPro ignores the typical mesh effects.
The mesh effects of TextMeshPro (eg VertexJitter, VertexColorCycler etc) are very unique in their implementation and can only be used for TextMeshPro...

I think that an easy way to implement a common mesh effect is necessary.

This project provides a base class for mesh effect.
It works well not only for standard Graphic components (Image, RawImage, Text, etc.) but also for TextMeshPro and TextMeshProUGUI.
Just change your mesh effect a few places, it will support TextMeshPro!

Let's decorate your TextMeshPro with effects!

Features

Works well not only for standard Graphic components (Image, RawImage, Text, etc.) but also for TextMeshPro and TextMeshProUGUI.
Support multiple fonts.
There is no useless allocation.
Good performance.
You can implement MeshEffect with VertexHelper or Mesh.
Easily make your mesh effect support TextMeshPro. See detail
If your project does not use TMPro, add "NOT_USE_TMPRO" symbol. Or uncomment the first line of BaseMeshEffect.cs.

//#define NOT_USE_TMPRO // If your project does not use TMPro, uncomment this line.

Demo

WebGL Demo

Usage

Download MeshEffectForTextMeshPro.unitypackage from Releases.
Import the package into your Unity project. Select Import Package > Custom Package from the Assets menu.
Add any effect component to TextMeshPro from Add Component in inspector or Component > MeshEffectForTextMeshPro > ... menu.
Adjust the parameters of the effect as you like, in inspector.
If your project does not use TMPro, add "NOT_USE_TMPRO" symbol. Or uncomment the first line of BaseMeshEffect.cs.

//#define NOT_USE_TMPRO // If your project does not use TMPro, uncomment this line.

Enjoy!

Requirement

Unity 5.5+ (including Unity 2019.x)
TextMeshPro v1.0.0+

Development Note

Make your mesh effect supports TextMeshPro

Change the base class from BaseMeshEffect to Coffee.UIExtensions.BaseMeshEffect.

// Before
public class YourMeshEffect : BaseMeshEffect
or
public class YourMeshEffect : MonoBehavior, IMeshModifier

// After
public class YourMeshEffect : Coffee.UIExtensions.BaseMeshEffect

If you are using specific methods, override it properly.

OnEnable, OnDisable, LateUpdate, OnDidApplyAnimationProperties, OnValidate, ModifyMesh.
Call base.xxx except ModifyMesh.

// Before
void OnEnable ()
{
    ...
}
void OnDisable ()
{
    ...
}
...
void ModifyMesh (VertexHelper vh)
{
    ...
}

// After
protected override void OnEnable ()
{
    base.OnEnable();
    ...
}
void OnDisable ()
{
    base.OnDisable();
    ...
}
...
public override void ModifyMesh (VertexHelper vh)
{
    //base.ModifyMesh(vh);  <- ModifyMesh's base method is unnecessary.
    ...
}

Change graphic.SetVerticesDirty to SetVerticesDirty

// Before
public bool horizontal { get { return this.m_Horizontal; } set { this.m_Horizontal = value; graphic.SetVerticesDirty(); } }

// After
public bool horizontal { get { return this.m_Horizontal; } set { this.m_Horizontal = value; SetVerticesDirty(); } }

If there are compile errors, remove them.
