classAttractToPoint

@codexo/exojs-particles / particles / stable

Pulls every live particle toward a fixed point in the system's local coordinate space. Acceleration magnitude is `strength` (units / s²), applied along the direction `(point − particle)`. The optional `falloff` radius softens the pull near the center — particles within `falloff` units lerp the strength linearly to zero, preventing the singularity at `r = 0` from yielding infinite acceleration. Use cases: orbit anchors, pin emitters to a moving target, simulate a "black hole" pickup. For repulsion, use RepelFromPoint; for tangential motion, layer with OrbitalForce. GPU-eligible.
