Declaration

Declaration
void scaleMatrix33(Matrix33 *m, FixedPoint<> s)

Scale a 3x3 matrix by a scalar.

ParameterTypeMeaning
mMatrix33 *The matrix to scale.
sFixedPoint<>The scalar to scale by.

Returns: Nothing (void).

Example

C++ example
#include "psyqo/soft-math.hh"

// Assume these named values have been initialized with valid data:
// Matrix33 * m
// FixedPoint<> s

psyqo::SoftMath::scaleMatrix33(m, s);

Why use it

Fixed-point inputs keep console behavior deterministic and avoid software floating-point work.

Trade-offs and warnings

Stay within the documented range and account for quantization before chaining several operations. Pointer/reference arguments are borrowed unless the source contract says otherwise; keep them valid for the complete operation and never assume null is accepted.
