After attaching object isn't asking permission:

integer prm;

default
{
   attach(key id)
    {
        if (id)
         {
    llRequestPermissions(llGetOwner(),PERMISSION_TAKE_CONTROLS);
        }
    }
    
    run_time_permissions(integer perm)
    {
        if (perm)
        {
            prm = TRUE;
            llTakeControls(CONTROL_UP|CONTROL_DOWN, TRUE, FALSE);
        }
    }
    
    control(key id, integer level, integer edge)
    {
        if (prm == TRUE)
        {
            if (CONTROL_UP)
        {
            llMoveToTarget(llGetPos()+<0,0,1>,10);
        }
        }
    }
}

Whatever I do, go up, want to go to all directions

 

integer prm;

         {
    llRequestPermissions(llGetOwner(),PERMISSION_TAKE_CONTROLS);
        }
    }

    {
        if (perm)
        {
            prm = TRUE;
            llTakeControls(CONTROL_UP|CONTROL_DOWN|CONTROL_FWD|CONTROL_BACK, TRUE, FALSE);
        }
    }
    
    control(key id, integer level, integer edge)
    {
        if (prm==TRUE)
    {
        if (CONTROL_UP)
        {
            llSetStatus(STATUS_PHYSICS, TRUE);
            llMoveToTarget(llGetPos()+<0,0,1>,.1);
            
        }
        else if (CONTROL_DOWN)
        {
            llSetStatus(STATUS_PHYSICS, TRUE);
            llMoveToTarget(llGetPos()-<0,0,1>,.1);
        }
    else if (CONTROL_FWD)
        {
            llSetStatus(STATUS_PHYSICS, TRUE);
            llMoveToTarget(llGetPos()+<0,1,0>,.1);
        }
    else if (CONTROL_BACK)
        {
            llSetStatus(STATUS_PHYSICS, TRUE);
            llMoveToTarget(llGetPos()-<0,1,0>,.1);

    control(key id, integer level, integer edge)
    {
        if (prm==TRUE)
    {
        if (CONTROL_UP)
        {
            llSetStatus(STATUS_PHYSICS, TRUE);
            llMoveToTarget(llGetPos()+<0,0,1>,.1);
            
        }
 

 

And it s normal , because in this piece of code , CONTROL_UP has always the value True . The test if ( CONTROL_UP) is not what you expect to do really

In fact you need to check the variables in parameters of the event ( named level and edge , in your case )

For instance by ( but it may depend of other comportments you desire about your HUD , sometimes you will need to check a combination of the variables  level and edge , sometimes only the variable level , etc ..  ) :

if ( level & CONTROL_UP)  ...

else if ( level & CONTROL_DOWN)  ...

else if ( level & CONTROL_RIGHT)  ...

etc ...

OR BY :

if ( edge & CONTROL_UP)  ...

else if ( edge & CONTROL_DOWN)  ...

else etc ...

 

In addition , yourscript , in its actual version , spamming "llSetStatus(STATUS_PHYSICS, TRUE);" ( you may around 40 events per seconds , if you let the key pressed , so , it s costly to set physics 40 times per seconds )

It should be avoided  , in setting physics on , only one time 

 

For your information :

• integer level – bitfield of CONTROL_* flags, non-zero while one or more keys is being held down.  
• integer edge – bitfield of CONTROL_* flags, non-zero when one or more keys have been just pressed or released.

How to move forward to the avatar's front?

You need to use a vector with the Y and Z value to zero; for instance <1,0,0>

and  you multiply it by the rotation of the avatar , so , for instance <1,0,0> * llGetRot() for an object attached

  

integer prm;

move(vector v)
{
    llMoveToTarget(llGetPos()+v*llGetRot(),.1);
}
default
{
   state_entry()
   {
        llRequestPermissions(llGetOwner(),PERMISSION_TAKE_CONTROLS);
    }
   attach(key id)
    {
        if (id)
         {
            llRequestPermissions(id,PERMISSION_TAKE_CONTROLS);
        }
        else
        {
            llSetStatus(STATUS_PHYSICS, FALSE);
        }
    }
    
    run_time_permissions(integer perm)
    {
        if (perm)
        {
            prm = TRUE;
            llTakeControls(CONTROL_UP|CONTROL_DOWN|CONTROL_FWD|CONTROL_BACK, TRUE, FALSE);
            llSetStatus(STATUS_PHYSICS, TRUE);
        }
    }
    
    control(key id, integer level, integer edge)
    {
        if ( level & CONTROL_UP)
        {
            move( <0,0,1.0 >);    
        }
        else if ( level & CONTROL_DOWN)
        {
            move( <0,0,-1.0 >); 
        }
        else if ( level & CONTROL_FWD)
        {
            move( <1.0, 0, 0 >);
       }
        else if ( level & CONTROL_BACK)
        {
            move( <-1.0, 0, 0 >); 
        }  
    }

}

Use Control_up and control_down for the forwards and backwards movements, use Page_up and page_down for verticals

CONTROL_FWD and CONTROL_BACK for forwards and backwards. (W/ArrowUp and S/ArrowDown)

CONTROL_UP and CONTROL_DOWN for vertical up and down. (E/PageUp and C/PageDown)

You had an extra apostrophe there.

The Raspberry Pi 400 keyboard is hampering my already-bad typing by mostly missing out letters, and on the odd occasion, repeating them. I'm going to try spilling coffee on and dropping crumbs into it to try and get it into my normal keyboard state.

Need an example page link for move <...>

from what you have posted it seems that you want an impulse engine, that applies impulse/movement to the agent when the keyboard controls are pressed

the most complete agent impulse engine source code is Flight Feather by Argent Stonecutter, which can be obtained from his store here:

Short answer is have a look at the wiki ages for rotation for use of * and / when applying rotations; to rotate a vector we multiply it by a rotation, adding vector to vector just performs a translation.

Long answer, the same as the short answer, but additionally and in particular as recently described by MollyMews,   quarternions get it right where eulers get it wrong in certain cases.

 

 

 

 

 

 

(I'm going to get hammered over this, I'm building myself a fallout shelter and going into it until it seems safe again).

@redpurple Carpaccio But you used  v*llGetRot() instead v+llRot2Euler(llGetRot()), Why?

I use llGetPos()+v*llGetRot() because llMoveToTarget uses region coordinates . 

The vector v <1,0,0> is in local coordinates linked in the frame of reference of avatar :

it means "front of avatar" , but of course , in region coordinates , v can t have <1,0,0> as value .

So i need to convert it in the frame of refrence of the region . it s exactly what does a multiplication of a vector by a quaternion

 

LLRot2Euler gives the axis of rotation . So , it s wrong .

For instance let s guess v was <100, 0,0>  .  Let s guess a rotation of PI/4

By evidence , the vector V converted , should get the same length ( same magnitude ) 

V  * llGetRot() gives again a vector with 100 of magnitude . For instance , magnitude ( 100 / root(2) = 70.71 , 100/ root(2) = 70.71 , 0 ) = 100

Your formula will give a vector between  <100 , 0 ,-1 > and <100, 0,1> and won't give a constant magnitude of 100 and  doesn t turn with the angle of rotation. Your formula is false in this case 

An another point who should convince you that llRot2Eurler shouldn t be used  for this case  . LlRot2Euler gives the axis of rotation from a quaternion .

But the rotation for an avatar  has always its axis along the Z coordinates  . So when you add v+llRot2Euler(llGetRot())

you don t change the X and Y coordinates
