In hot loops, Lua allocations from math operations create GC pressure that hurts frame rates. xmath mutates an existing scratch buffer in place so no new objects are created per frame.
Pre-allocate scratch variables at module scope and replace per-frame allocations with xmath calls that mutate results in place.

To reduce Lua GC pressure in Defold hot loops, use in-place xmath optimizations that mutate a pre-allocated scratch buffer instead of creating new vector3, vector4, quaternion, or matrix objects per frame.
The best way to pre-allocate scratch variables for Defold math calculations is to define them at module scope or during initialization, then use xmath calls to write results directly into these existing buffers inside update() methods.
In-place mutation with the defold-xmath library works by writing all mathematical operation outputs directly into the first argument provided, ensuring no new object allocations are performed during game logic execution.
Yes, you can use xmath optimizations for regular Defold vector3, vector4, quaternion, and matrix operations by replacing standard API calls with xmath equivalents that mutate pre-allocated scratch buffers in place to avoid garbage collection overhead.
Yes, you need the defold-xmath library, such as thejustinwalsh/defold-xmath, and a pre-allocated scratch buffer to perform zero-allocation math in Defold and eliminate per-frame object creation in hot loops.
You should avoid using in-place xmath optimizations in Defold game logic outside of performance-critical hot loops, as the library requires a pre-allocated scratch buffer and mutates the first argument, which is unnecessary overhead for standard math operations not causing GC pressure.
