BaseVertexEffect Change to BaseMeshEffect

Unity Engine
1

Hello,
BaseVertexEffect had a virtual method that gets a list of UIVertex
which i used to add vertices and reorder the existing ones…
Now I get a mesh and tried to add vertices and colors but it just causes the text to disappear
I have also tried adding indices but it doesnt work either…
And I cannot go back to BaseVertexEffect because it is forcing me to use BaseMeshEffect by an error.

The code i used to have in 5.0: Outline - Pastebin.com

Hi,
I had your same issue. To solved it, I just followed the same approach the new Shadow effect does.

    #if UNITY_5_2
    public partial class MyEffect : BaseMeshEffect
    #else
    public partial class MyEffect : BaseVertexEffect
    #endif
    {
        #if UNITY_5_2
        public override void ModifyMesh (Mesh mesh)
        {
            if (!this.IsActive())
                return;

            List<UIVertex> list = new List<UIVertex>();
            using (VertexHelper vertexHelper = new VertexHelper(mesh))
            {
                vertexHelper.GetUIVertexStream(list);
            }

            ModifyVertices(list);  // calls the old ModifyVertices which was used on pre 5.2

            using (VertexHelper vertexHelper2 = new VertexHelper())
            {
                vertexHelper2.AddUIVertexTriangleStream(list);
                vertexHelper2.FillMesh(mesh);
            }
        }
        #endif

        public void ModifyVertices(List<UIVertex> verts)
        {
                // you code goes here
        }

Notice that my declaration uses BaseMeshEffect when 5.2 and BaseVertexEffect otherwise.

Also notice, that the list vertices now has triangles instead of quads.

Thanks! Didnt notice they updated the code for the shadow effect.
Ill check that out as soon as I can

Thanks for the example fpuig. Is this UI source for 5.2 beta available yet thought? The latest update I see on the Bitbucket repo is from April…

Edit: Decompiling seems to be good enough for now.

Thank you so much for sharing the solution! Works great!
