I see. Well great enjoy your hobby.
It's impossible for *"Nothing changed" to change. It is possible that the change was too small. After all we moved the vecTarget so something change. So let's assume the change is just too small. Than try this.
Code:
vec_set( vecTarget, hit.x);
vec_set ( vec_temp, hit.nx);
vec_normalize ( vec_temp, 555);// Huge change
vec_add ( vecTarget, vec_temp);


If you still see no change something else is happening.
If you see a big change, than adjust 555 down until close to correct.

I also don't understand this lerp
Code:
vec_lerp ( camera.x, camera.x, vecTarget, time_step );]

The value of Time_step is a small decimal. It's not collecting or adding to anything or itself. This could be a your big problem.

Try

Code:
..............
var range = 0;
.............

if(Taget_hit)
{
.........
if (range < 1)
range += time_step;
}
else
{
.....
range = 0;
}

vec_lerp ( camera.x, camera.x, vecTarget, range );]


I would like you to understand, I don't use this engine, I haven't in over a year. I don't have this engine installed and I work from memory, logic and looking in the manual to answer your questions. Finally I get nothing out of helping you, I answer for your benefit, my involvement is volunteer and I can stop if it's not to you're taste.

We all have jobs or other things to take our time. I currently am working on a project in another community and also learning a second engine, so my free time has other things to fill it than answering here.
