classApplyForce

@codexo/exojs-particles / particles / stable

Adds a constant 2D acceleration to every live particle's velocity each frame. Use for gravity (`new ApplyForce(0, 980)`), wind, or any uniform force field. Force is applied to all particles equally — for per-particle variation, layer multiple ApplyForce modules with different gates. GPU-eligible: implements UpdateModule.wgsl so this module runs in the system's compute shader on WebGPU backends with no CPU readback.
