Effect of Force on particles with a shift in Time (+hip file)

01. The @grad attribute is set so that you can influence the properties of movement along the Y axis (if necessary)
02. The @class attribute in order to be able to influence in the DOP on each object separately.

3. 2 “anim”  and “delay” channels are added.
3. The “anim” channel have animation from 0 to 1.
4. VEX Expression with @grad and @amp:

float anim = chf(“anim”,@Time-@class*ch(“delay”));
float grad = clamp(@grad+anim,0,1);
force=fit01(anim,0, force)*pow(grad,3);
amp = fit01(anim,0, amp);

5. 4. VEX Expression without @grad and @amp:

float anim = chf(“anim”,@Time-@class*ch(“delay”));
force=fit01(anim,0, force);
