Clamping smooth approach?

[Edwin]

Hello, people I have this script that creates smooth approaching:

var distance = target - current;

if (abs(distance_x) > 0.1) {
    current += ( target - current ) * speed;
} else {
    current = target;
}

This code makes smooth approaching but current will be faster depending of target distance. How I can just clamp the speed of it?

If you want linear acceleration, you can use lerp(); Did you try it yet?
like current=lerp(current, target, 0.2);

This is practically the same function. Lerp don't clamp the speed (like the code above), so I need to make my own script with speed clamping.

Oh you mean you go faster than your max speed? If so clamp it with clamp() right after the code you have and you'll be set. Starting to doubt I understand what's the problem, hahahaha

There is no max speed. You increase it with the third argument in the lerp function. Try to make a room with large width and medium height and try to put the mouse to the farthest point from the object in which you use lerp function and see the results. Then, so to speak, I need to create a max speed.

Do you just mean this?

var distance = target - current;

if (abs(distance_x) > 0.1) {
   current += clamp(( target - current ) * speed, min_speed, max_speed);
} else {
   current = target;
}

Another way is:

var xdist = targetx-currentx;
var xspd = min(max_spd,abs(xdist))*sign(xdist);
// Repeat for y

if (abs(distance_x) > 0.1) {
   current += clamp(( target - current ) * speed, min_speed, max_speed);
} else {
   current = target;
}

That clamps the speed, but it changes the value too fast.
