How can I move an object to a destination? For example, if the destination I want to move the object is on the second floor in a particular room of a house, how would I do this? There wouldn't happen to be a command that could take care of this would there?

DB and Other Questions,

Are you wanting the object to translate(instantaneously be positioned from one place to the other, without time), or to move, over time, to this new destination? I will exaplain either way to you, once you answer this question.

Nano,

I want to move the object over a period of time, like a man walking to that destination.

Thanks,

DB&OQ

DB and Other Questions,

Use a series of waypoints to accomplish this. A waypoint is exactly that, a point within space, 3D or 2D, which acts as a destination. So, create an array of points(coordinates x,y,z), in a series, in an order you wish for the a.i. to follow. Starting with the first point, find the angle between the object and the point. Move the object in that direction calculated, checking the distance between the two constantly.

If the distance between the two are within, let's say 1 unit, then switch the object's destination to be the next waypoint. This is not too specific, however, I will write up a quick program in 3D to show you these words in action.

Oh nm the email I sent I misunderstood you. I didn't even see this thread. Pathfinding is definately the easiest to do that with. If you are using CSHOP and the .csm importer it is even easier as you can place the way points when you build the map. You can then start off with some easy code like if object is within 1 unit of a waypoint then it is at that waypoint, point the object to the next way point and move, when within 1 unit of that way point ... point at the next and so on. You can make it as complex or simple as you desire. You could even place small collision boxes (static for speed) and use their collisions to move to the next waypoint.

DB and Other Questions,

I am still in the process of writing the example program for you, just busy in life. For now, check out this great link that the good man, Baggers, has posted in another thread. It's an a.i. system, called pathfinding.

Thank you Baggers.
