My 5'th resource @ Garagegames "3D Arrow aiming to objective target"

http://www.garagegames.com/community/blogs/view/16675

This resource will give you a 3D arrow (or any object you like) aiming to the target object you want.

This is the preview of how this works.


you can download it here www.geocities.com/herrudarmadi/3darrow.zip
place it on data/shapes/direction/arrow.dts

first add this to your server/game.cs

$aimTarget = 0;

function GameConnection::AimTarget( %this )
{ 
 if($aimTarget)
 {       
    %player = %this.player;
    %target = $aimTarget;
  
    %playerTrans = (%player.getTransform()); 
    %xPlayer = getWord(%playerTrans, 0);
    %yPlayer = getWord(%playerTrans, 1); 
    %zRot = getWord(%playerTrans, 5);
    %playerRot = getWord(%playerTrans, 6);
     
    %targetPosition = (%target.getPosition());
    %xTarget = getWord(%targetPosition, 0);
    %yTarget = getWord(%targetPosition, 1);
     
    %xDiff = %xTarget - %xPlayer;
    %yDiff = %yTarget - %yPlayer;
  
    // dont have to change it to degrees
    // torque engine automatically change it to degrees
    %rotToTarget = mAtan(%xDiff, %yDiff);
  
    if(%zRot < 0)
         %playerRot = (2 * 22/7) - %playerRot;
            
      // multiply by -1 because the rotation in 3dspace is 
      // oppositing the guiobjectview rotation
      %rotation = -1 * (%rotToTarget - %playerRot);
         
      commandToClient(%this, 'SetDirection', %rotation);
   }
   %this.schedule(100, AimTarget);
}

on the client/ui/playgui.gui add

new GuiObjectView(direction) {
    canSaveDynamicFields = "0";
    Profile = "GuiDefaultProfile";
    HorizSizing = "center";
    VertSizing = "bottom";
    position = "244 94";
    Extent = "149 149";
    MinExtent = "8 2";
    canSave = "1";
    Visible = "1";
    hovertime = "1000";
    applyFilterToChildren = "1";
    cameraZRot = "0";
    forceFOV = "0";
    lightDirection = "-0.57735 -0.57735 -0.57735";
    lightColor = "0.6 0.58 0.5 1";
    ambientColor = "0.3 0.3 0.3 1";
    emapAmount = "1";
 };

and on the client/playgui.cs add

function PlayGui::onWake(%this)
{
 // Turn off any shell sounds...
 // alxStop( ... );
 $enableDirectInput = "1";
 activateDirectInput(); 
   direction.setObject("gb","mod/data/shapes/direction/arrow.dts","","");

 // Activate the game's action map
 moveMap.push();
}

function clientCmdSetDirection(%rotation)
{
 direction.setRotation(0,  %rotation );
}

how to use it ?

just set the $aimTarget to any object id in your mission.
then call the gameConnection method aimTarget().

that's it, hope this resource usefull. cheers!
