I started to work on my new agk project and made this as i nead it for my editor.
If anyone have suggestions on doing it better so please tell me

rem
rem AGK Application
rem
SetVirtualResolution( 480, 480 )
SetCameraPosition(1,0,0,-300)
SetCameraRotation(1,0,0,0)
rem A Wizard Did It!
box= CreateObjectBox( 50,50,50 )
SetObjectPosition( box, -60, 0,0 )
box= CreateObjectBox( 50,50,50 )
SetObjectPosition( box, 0, 0,0 )
box= CreateObjectBox( 50,50,50 )
SetObjectPosition( box, 60, 0,0 )
do
 RotateObjectGlobalX( box, 1 )
 REM // Check if user selects an 3d object
 if GetRawMouseLeftReleased()
    rx#=Get3DVectorXFromScreen( GetRawMouseX(), GetRawMousey() )*100000
    ry#=Get3DVectorYFromScreen( GetRawMouseX(), GetRawMousey() )*100000
    rz#=Get3DVectorZFromScreen( GetRawMouseX(), GetRawMousey() )*100000
    temp=0
    REM// seams like i nead to check for raycast hits on all the objects?
    for t=10001 to 10003
        temp=ObjectRayCast( t, getcamerax(1), getcameray(1), getcameraz(1), rx#, ry#, rz# )
        if temp>0
        temp=t
        exit
        endif
    next t
 if temp>0 then if temp<>box then box=temp
 endif
 print(box)
 Sync()
loop

No one found it usefull?

i have added a bunch of things to the editor and the progress goes well.
I only had to write my own scale function as the command havent bin added yet in beta 3 that iam using.

Time to move to the showcase section soon

Cheers.

Useful bit of code! It works nicely in a little 3d program I am toying around with, now the latest beta is out. I'm surprised no one else has commented, perhaps not many people are playing with 3D much yet. Saved me some time figuring it out, cheers!

looks useful too bad I did not see this sooner and made my own.

+ Code Snippet

createobjectbox(1,100,100,100)
movecameralocalz(1,-300)
createobjectbox(2,5,5,5)
setobjectcolor(2,255,0,0,255)
do

 worldX# = Get3DVectorXFromScreen( GetPointerX(), GetPointerY() ) * 800
    worldY# = Get3DVectorYFromScreen( GetPointerX(), GetPointerY() ) * 800
    worldZ# = Get3DVectorZFromScreen( GetPointerX(), GetPointerY() ) * 800

    worldX# = worldX# + GetCameraX( 1 )
    worldY# = worldY# + GetCameraY( 1 )
    worldZ# = worldZ# + GetCameraZ( 1 )

 obj=ObjectRayCast(1,getcamerax(1),getcameray(1),getcameraz(1), worldx#,worldy#,worldz#)
if obj
x as float
y as float
z as float
x=GetObjectRayCastX(0)
y=GetObjectRayCasty(0)
z=GetObjectRayCastz(0)
setobjectposition (2,x,y,z)
print ("object: "+str(obj))
print ( "X: "+str(x) )
print ( "Y: "+str(y))
print ( "Z: "+str(z))
endif
    sync()


    loop

It is useful because you can get the position where you clicked on the object.

You could make a top down placement system like rts with this:

+ Code Snippet


global aicount
aicount=3
createobjectplane(1,100,100)
movecameralocalz(1,-300)
createobjectbox(2,5,5,5)
setobjectcolor(2,255,0,0,255)
do

 worldX# = Get3DVectorXFromScreen( GetPointerX(), GetPointerY() ) * 800
    worldY# = Get3DVectorYFromScreen( GetPointerX(), GetPointerY() ) * 800
    worldZ# = Get3DVectorZFromScreen( GetPointerX(), GetPointerY() ) * 800

    worldX# = worldX# + GetCameraX( 1 )
    worldY# = worldY# + GetCameraY( 1 )
    worldZ# = worldZ# + GetCameraZ( 1 )

 obj=ObjectRayCast(1,getcamerax(1),getcameray(1),getcameraz(1), worldx#,worldy#,worldz#)
if obj
x as float
y as float
z as float
x=GetObjectRayCastX(0)
y=GetObjectRayCasty(0)
z=GetObjectRayCastz(0)
setobjectposition (2,x,y,z)
if getpointerpressed()
createobjectbox(aicount,5,5,5)
setobjectposition(aicount,x,y,z)
setobjectcolor(aicount,0,255,0,255)
aicount=aicount+1
endif
print ("object: "+str(obj))
print ( "X: "+str(x) )
print ( "Y: "+str(y))
print ( "Z: "+str(z))
endif
    sync()


    loop
