movement formula for 'move' command

[Duwul]

I've recently created a NPC that follows a certain path. The NPC uses the move command to move, so the time it takes is required. However, I can't get it to maintain a constant speed. Does anyone know a formula that can help me out? All help is appreciated.

The time should be something like (dx*dx + dy*dy)^0.5 / speed, I think.

[Duwul]

I actually had that, except I did not divide it by the speed at the end. I'll try it. Thanks.

EDIT: Well it worked. Thanks a lot!

I have attached a baddy script - it uses the move command. I made it initially for archaic, but it should help you.

But to the point:

NPC Code:

---

tx = targetx - x;

ty = targety - y;

dist = (tx*tx+ty*ty)^0.5;

nx = (tx/dist)*walkspeed;

ny = (ty/dist)*walkspeed;

---

Edit:

Then simply use

NPC Code:

---

move nx,ny,walkspeed,1+4+8;

---

etc.

Hope It helped

I guess a bit, but I'm only looking for an equation to put in 'time' of the move command, so that no matter the distance it moves, the walking speed remains the same. I am not using x+/x-/y+/y-.

try multiplying the distance by .05? dono

Ran into a problem. I made a npc that walks in a straight line on the along the x axis and while its moving in between the 2 points, it goes very fast. I guess the equation didn't work properly =/
Can anyone help me out with one that works?

try somethin like this

NPC Code:

---

if (mousedown) {

  dx = mousex - x;

  dy = mousey - y;

  dist = (dx^2+dy^2)^.5;

  speed = dist * .05;

  move dx,dy,speed,;

}
