how to make a character move?

[rubbish]

move speed? turn left or right?

[Silmaryls]

This is an interesting question.

Here is one way to do it :

Code: Select all

human.AnimationStates.PlayMode = BrumeAnimationParams.PLAY_LOOP;
// move
if (BrumeKeyboard.IsPressed(BrumeKey.W))
{
    // if !walking and !running
    if (human.Animation != animations[ANIM_WALK_start] && human.Animation != animations[ANIM_WALK_player] && human.Animation != animations[ANIM_run_player])
    {
        human.Animation = animations[ANIM_WALK_start];
    }
}
else if (BrumeKeyboard.IsPressed(BrumeKey.S))
{
    // if !walking & ! running
    if (human.Animation != animations[ANIM_walk_start_back] && human.Animation != animations[ANIM_walk_back] && human.Animation != animations[ANIM_run_back])
    {
        human.Animation = animations[ANIM_walk_start_back];
    }
}
else if (BrumeKeyboard.IsPressed(BrumeKey.A))
{
    // if not walking left
    if (human.Animation != animations[ANIM_walk_left] && human.Animation != animations[ANIM_run_left])
    {
        if (running)
        {
            human.Animation = animations[ANIM_run_left];
        }
        else
        {
            human.Animation = animations[ANIM_walk_left];
        }
    }
}
else if (BrumeKeyboard.IsPressed(BrumeKey.D))
{
    // if not walking right
    if (human.Animation != animations[ANIM_walk_right] && human.Animation != animations[ANIM_run_right])
    {
        if (running)
        {
            human.Animation = animations[ANIM_run_right];
        }
        else
        {
            human.Animation = animations[ANIM_walk_right];
        }
    }
}
else // no keys
{
    if (human.Animation != animations[ANIM_IDLE_stance])
    {
        human.Animation = animations[ANIM_IDLE_stance];

        // update pos en fontion du root object
        human.UpdatePos(inCar, car);
    }
}
// direction
BrumeVector newDir = camera5.Dir;
newDir.Y = 0.0f;
newDir.Normalize();
human.Orient(newDir, human.Up);


The source is from the GTA Vice City like projet. It quite old now but still interesting.
You can find the entire project here.

It shows how to use LOD, human animations, car physics, dynamic level loading and more. The more interesting to me was that it was really fast and without occlusion culling and streaming.

Once the animation is choosen you will need an event handler to update player's position :

Code: Select all

public void HumanAnimationEnd(BrumeObject sender)
{
    if (sender.Animation != null)
    {
        switch (sender.Animation.Name)
        {
            case "run_player": break;
            case "WALK_player": break;
            case "WALK_start": if (running) sender.Animation = animations[ANIM_run_player]; else sender.Animation = animations[ANIM_WALK_player]; break;
            case "walk_start_back": if (running) sender.Animation = animations[ANIM_run_back]; else sender.Animation = animations[ANIM_walk_back]; break;
            case "Run_stop": break;
            case "run_back": break;
            case "walk_back": break;

        }

        // update pos en fontion du root object
        if (!inCar)
        {
            human.UpdatePos(inCar, car);
        }
    }
}       


[rubbish]

hahaha~
that's what i want~
thx very much

[rubbish]

but...
where is the animation files &media files
i can't run the GTA Vice City like projet

[Silmaryls]

hehe it's normal...Vice City is a commercial game. When I said Vice City clone I was wrong. In fact the prject is reusing Gta objects.
So you will have to buy the game in order to run the project.

If you got the game you must unpack gta.img file using some tool like ImgTool.
Then modify the img paths in the project (should be just one) and run !

If you dont't have the game you can still out the source code and replace the objects by yours.

[rubbish]

for example
i press "w"
the tiny walk forward ,what's the walk speed?
press " d" then turn right and continue forward?how to do that?

[Silmaryls]

You have to compute the speed in a variable.
Tiny's forward animation doesn't include translation keys (if your are using the same model as me).
You will also have to compute a position change for the same reason. You can use the MoveScene method with something like that :

Code: Select all

O THANK YOU VERY MUCH
another question

can two animations run in the same time?
tiny "Wave"&"Walk" ?
three ?four??

[Silmaryls]

Not at the moment.

BrumeObject has only one Animation property.

[rubbish]

o...

but i want tiny "wave" & "Walk" at the same time....

can't achieve?

[Silmaryls]

Maybe by using an external tool to merge the animations ?

Otherwise you will have to wait for the feature (It's not planned for next release at the moment).

[rubbish]

what a pity

[Silmaryls]

It's life !
