Problem with HUD_GETCORNER

[stevev4v]

I have been tinkering with the sample code and thought I had pretty much figured how how this product works BUT I have run into a problem. This code works fine (but is not really what I need):

Tmp = HUD_CreateImage (Layer4, 0,0, 53,91, 32,32)
HUD_PositionObject Tmp, HUD_GetObjectX(Image)+10, HUD_GetObjectY(Image)+50
HUD_SetObjectRotation Tmp, Rand(0,360)
HUD_SetObjectScale Tmp, .25,.25
HUD_SetObjectColor Tmp, 100,100,100,.65
HUD_FX_SteadyMove Tmp, 0,Rand(0,-25)
HUD_FX_Scale Tmp, 2,2,1500
HUD_FX_AlphaFade Tmp, 0,2000
HUD_FX_AutoRemove Tmp, 2000 ; ...AND BYE

But the code below results in a "The specified HUD does not exist" error.

Tmp = HUD_CreateImage (Layer4, 0,0, 53,91, 32,32)
HUD_PositionObject Tmp, HUD_GetCorner(Image,3,0),HUD_GetCorner(Image,3,1)
HUD_SetObjectRotation Tmp, Rand(0,360)
HUD_SetObjectScale Tmp, .25,.25
HUD_SetObjectColor Tmp, 100,100,100,.65
HUD_FX_SteadyMove Tmp, 0,Rand(0,-25)
HUD_FX_Scale Tmp, 2,2,1500
HUD_FX_AlphaFade Tmp, 0,2000
HUD_FX_AutoRemove Tmp, 2000 ; ...AND BYE

Anybody know why?

Try GetObjectCoords

I did, it doesn't work either.

The point is why does HUD_GetObjectX work fine and HUD_GetCorner does not when used on the exact same HUD?

[tonyg]

Does 'Image' really contain your HUD ID?
Hud_GetCorner works with a HUD handle and returns the HUD corner X/Y.
This works for me...


Graphics3D 640, 480, 0, 2 : SetBuffer BackBuffer()
;my_timer=CreateTimer(60)
; INCLUDE SPRITE CANDY
Include "../sprite candy.bb"

; CREATE CAMERA, LIGHT, BACKGROUND
Cam   = CreateCamera()

; CREATE THE HUD
HUD%       = HUD_Create (Cam)
Hud_x = HUD_GetCorner(hud,3,0)
hud_y = HUD_GetCorner(hud,3,1)
Print hud_x + " " + hud_y
WaitKey()

Try GetObjectCoords

Okay, that did work. It threw me off that the syntax for GetObjectCoords is different than GetCorner:

HUD_GetCorner ( HUD_Handle%, corner%, getY% )

HUD_GetObjectCoords ( Object_Handle%, value$, [corner%] )

Okay, so it seems strange to me that these two commands do basically the same thing except that one works for Huds and the other for objects. Maybe GetObjectCorner and keeping the same syntax would have made more sense.

Anyhow, thanks for the help!

We discussed this point during beta. Because HUD_GetObjectCoords does more than just get a corner of an object, Mike decided to leave it as it is.
