Mesh:setVertex
| Available since LÖVE 0.9.0 |
| This function is not supported in earlier versions. |
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.

| This variant is not supported in earlier versions. |
Synopsis
Mesh:setVertex( index, attributecomponent, ... )
Arguments
number index- The index of the the vertex you want to modify (one-based).
number attributecomponent- The first component of the first vertex attribute in the specified vertex.
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 vertex format. A standard Mesh that wasn't 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 data type is "float", or 1 if its data type is "byte".

Synopsis
Mesh:setVertex( index, vertex )
Arguments
number index- The index of the the vertex you want to modify (one-based).
table vertex- A table with vertex information, in the form of
{attributecomponent, ...}.
Returns
Nothing.
Notes
The table indices are in the same order as the vertex attributes in the Mesh's vertex format. A standard Mesh that wasn't 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 data type is "float", or 1 if its data type is "byte".
Function
Sets the vertex components of a Mesh that wasn't created with a custom vertex format.
Synopsis
Mesh:setVertex( index, x, y, u, v, r, g, b, a )
Arguments
number index- The index of the the vertex you want to modify (one-based).
number x- The position of the vertex on the x-axis.
number y- The position of the vertex on the y-axis.
number u- The horizontal component of the texture coordinate.
number v- The vertical component of the texture coordinate.
number r (1)- The red component of the vertex's color.
number g (1)- The green component of the vertex's color.
number b (1)- The blue component of the vertex's color.
number a (1)- The alpha component of the vertex's color.
Returns
Nothing.

Synopsis
Mesh:setVertex( index, vertex )
Arguments
number index- The index of the the vertex you want to modify (one-based).
table vertex- A table with vertex information.
number [1]- The position of the vertex on the x-axis.
number [2]- The position of the vertex on the y-axis.
number [3]- The u texture coordinate. Texture coordinates are normally in the range of [0, 1], but can be greater or less (see WrapMode.)
number [4]- The v texture coordinate. Texture coordinates are normally in the range of [0, 1], but can be greater or less (see WrapMode.)
number [5] (1)- The red color component.
number [6] (1)- The green color component.
number [7] (1)- The blue color component.
number [8] (1)- The alpha color component.
Returns
Nothing.
