[4.2.0] buildOrderedIndices method of Mesh2D game object

[rexrainbow]

Version

• Phaser Version: 4.2.0

• Operating system: win11

• Browser: chrome

Description

Test case , build the same vertices via different methods

• setRenderAsTriangles
• setUseOrderedIndices
• buildOrderedIndices

And user can drag red-circle to move the vertex.

The last one, ordered quad

mesh.buildOrderedIndices(2, true)
// renderAsTriangles = false

seems to be wrong, especially the bottom of triangle.

1st and 2nd methods looks fine.

Codex gives me these warning :

• Warning: this optimization is intended for stable meshes where paired
• triangles form valid convex quads. It is not suitable for concave, folded,
• self-intersecting, or freely deformed meshes. In those cases use
• setRenderAsTriangles(true) to preserve the original triangle topology.

So, it is not a bug, might add some warning messages in Mesh2D game object.
