Moving a character to a point

[rubbish]

i select a point at the floor by mouse
and then tiny move there

how to do that?

You will have to compute the 3D point in space. This is impossible without a distance value.
In fact you can get the ray to the pointed direction using object Picking. But you will need to stop the ray in order to compute the cliked position.
For that you should use a plane (floor) or some 3D object and : compute ray/plane intersection or ray/object intersection in order to get clicked point.
Once you have it, just compute direction = "cliked point" - "tiny.Pos" to get the direction vector and update it like always : tiny.Pos += direction * factor;

some difficult
how to use object Picking?it's hard to unstand....

[Silmaryls]

Object picking is not too hard in Brume.

Just take a look at this post.

[rubbish]

I USE VERSION 1.2 ...
but it can't find pickobject...

[Silmaryls]

You have to upgrade to 1.4.

how to compute ray/plane intersection or ray/object intersection in order to get clicked point?

[rubbish]

where r u??
my dear friend Silmaryls

[Silmaryls]

As I said above : Just take a look at this post.

[rubbish]

i can't understand how to compute ray/plane intersection or ray/object intersection in order to get clicked point?

[rubbish]

give me some idea?

[Silmaryls]

Ok, first you have to create a terrain or a plane (maybe your grid mesh ?).
You can use a mesh or BrumeSquareTextured. Let's name it 'ground' !

Once you're ready, you get the ray where your mouse is pointing :

Code: Select all

BrumeRay ray = this.ActiveCamera.GetRayFromMouse();


Then you use PickObjects to get intersections with the ray. (you have to get all intersections as a character may be intersecting the ray, but all you want is the ray/ground intersection)

Code: Select all

List<BrumeObject> objects;
List<float> distances;
this.PickObjects(ray, out objects, out distances);


now, you have to test if the objects list contains your ground object (plane or terrain).
If it is, just get the corresponding distance and compute the intersection point like this :

Code: Select all

BrumeVector intersectionPoint = ray.Pos + ray.Dir * distance;


It's up to you now !

OK,and how to compute direction = "cliked point" - "tiny.Pos" to get the direction vector?
It moved so strang.
The Tiny.Orient = direction??

[MoDDiB]

BrumeVector dir = "cliked point" - "tiny.Pos";
tiny.Orient( dir , the good up vector );
nothing more but before orienting tiny you may have to do some dir.X = -dir.X changes it depends on your model orientation.

[rubbish]

OMG...make a mistake...make tiny move so quickly.....
Maybe the point is called waypoint...
But the Orient is wrong??
Do some dir.X = -dir.X changes it depends on your model orientation?
What's that mean??
