## vec_lerp(**
**VECTOR* v,VECTOR* v1,VECTOR* v2,var f);

interpolates the vector **v** between **v1** and **v2** according to the factor **f**.

### Parameters:

**v** |
**
VECTOR**, **ANGLE**, or **COLOR** to interpolate between v1 and v2 |

**v1** |
first vector |

**v2** |
second vector |

**f** |
interpolation factor |

### Modifies:

**v **- will be interpolated between** v1 **and** v2 **according to the factor** f**

### Speed:

Fast
### Algorithm:

v = (1-f)*v1 + f*v2

### Example (lite-C):

*// the following command sets the position vector at halfway between my and you*
vec_lerp(position,my.x,you.x,0.5); **
**// the following function interpolates a position, color, or angle to a target value during a time interval t
function time_lerp(var* v,var* vtarget,var time)
{
wait(1); *// put the function in the scheduler for being identified by proc_kill*
if (NULL != me)
proc_kill(5); *// terminate previous time_lerp calls of the current entity*
var vstart[3];
vec_set(vstart,v);
var t;
if (time > 0)
for(t=time_frame; t < time; t += time_frame) {
vec_lerp(v,vstart,vtarget,t/time);
wait(1);
}
vec_set(v,vtarget);
}
