{{newin|[[0.9.0]]|090|type=function}}
Sets the properties of a vertex in the Mesh.

In versions prior to [[11.0]], color and byte component values were within the range of 0 to 255 instead of 0 to 1.
== Function ==
{{newin|[[0.10.0]]|100|type=variant}}
=== Synopsis ===
<source lang="lua">
Mesh:setVertex( index, attributecomponent, ... )
</source>
=== Arguments ===
{{param|number|index|The index of the the vertex you want to modify (one-based).}}
{{param|number|attributecomponent|The first component of the first vertex attribute in the specified vertex.}}
{{param|number|...|Additional components of all vertex attributes in the specified vertex.}}
=== Returns ===
Nothing.
=== Notes ===
The arguments are in the same order as the vertex attributes in the Mesh's [[Mesh:getVertexFormat|vertex format]]. A standard Mesh that wasn't [[love.graphics.newMesh|created]] with a custom vertex format will use two position numbers, two texture coordinate numbers, and four color components per vertex: x, y, u, v, r, g, b, a.

If no value is supplied for a specific vertex attribute component, it will be set to a default value of 0 if its [[AttributeDataType|data type]] is "float", or 1 if its data type is "byte".
