physics_particle_set_radius(radius)
| 参数 | 描述 |
|---|---|
| radius | The radius (in pixels) of the particle fixture. |
返回： N/A（无返回值）
With this function you can set the radius (in pixels) for the
particles in a physics simulation. This function is global
in scope, in that it will change the radius not just for new
particles created after the change, but also for those already
present in the simulation.
physics_particle_set_radius(15);
physics_particle_set_density(0.5);
physics_particle_set_damping(1);
physics_particle_set_gravity_scale(1);
The above code will set the base properties for all particles in the simulation.
