Triangle

The Triangle class provides functionalities for creating, manipulating, and drawing triangles.

class Triangle

This class represents a triangle with three vertices and a color.

new(vec2_a, vec2_b, vec2_c, color)

• vec2_c (table) – The third vertex of the triangle.

• color (table) – The color of the triangle.

Returns:

A new instance of Triangle.

draw()

Draws the triangle using the specified vertices and color.

get_vec2s()

Returns the vertices of the triangle.

Returns:

A table containing the vertices of the triangle.

get_vec2_a()

Returns:

The first vertex of the triangle.

get_vec2_b()

Returns:

The second vertex of the triangle.

get_vec2_c()

Returns:

The third vertex of the triangle.

Set_vec2s(...)

Sets the vertices of the triangle.

Set_vec2_a(x, y)

Sets the first vertex of the triangle.

Parameters:

• x (number) – The x-coordinate.

• y (number) – The y-coordinate.

Set_vec2_b(x, y)
