Description

Overview

GMLinear is an implementation of matrix and vector operations in pure GML. You can use it to simplify many common calculations in 2D and 3D geometry and implement algorithms/formulas involving linear algebra. Hard-coded optimized functions are available for 2D, 3D and 4D vectors and 2x2, 3x3 and 4x4 matrices.

Examples

vec1_3d = [3, 4, 5];
vec2_3d = [1, 2, 3];
mat_3x3 = r33(
    1, 0, 0,
    0, 0, 1,
    0, 1, 0
);
vec_sum = r3_add(vec1_3d, vec2_3d); //[4, 6, 8]
dot_prod = r3_dot(vec1_3d, vec2_3d); //26
cross_prod = r3_cross(vec1_3d, vec2_3d); //[2, -4, 2]
vec_mult = r33_transform(mat_3x3, vec1_3d); //[3, 5, 4]
