how to convert sprite to mesh or to a polygon ???
i need the the sprite have the"mesh collide "with the particle collider! but the sprite can't add the "mesh filter",so i want use the sprite-wireframe to Extrusion a polygon! !
by the way i want to know: how to add the "tag"use the script and how to change component"World Particle Collider-Collision Energy Loss " use the script to change the value?? thank you!!:)!
A sprite does not have a wireframe. A sprite is likely some form of Quad. If you are using a polygon collider on the sprite, and if the polygon is a single path of points, you can use the Triangulator scrip from the Unity Wiki with the path to produce a mesh. But there is some heavy lifting involved in building this solution.
In general you can convert Sprite to Mesh with this:
Mesh SpriteToMesh(Sprite sprite)
{
Mesh mesh = new Mesh();
mesh.vertices = Array.ConvertAll(sprite.vertices, i => (Vector3)i);
mesh.uv = sprite.uv;
mesh.triangles = Array.ConvertAll(sprite.triangles, i => (int)i);
return mesh;
}
That actually looks like it would work. Though wouldn't you also need to add the $$anonymous$$eshFilter and $$anonymous$$eshRenderer?
I think you can assign that generated mesh directly to $$anonymous$$eshCollider, but I didn't try that yet.
vryzdal..can you help me please understanding lambda expression...
