GLOB_WORLD_ORIGO_OFFSET always returns Zero

runxel — Tue, 14 Sep 2021 11:32:09 GMT

Hey there, found another bug:
GLOB_WORLD_ORIGO_OFFSET_X (and _Y) always return 0 (zero).

Tested with AC 23 and 24.

Where are you using it?
It doesn't work in Parameter (Master) script.

Hey Barry, I know. I'm using it in the 2D script.
There is even an example code in the reference manual:

add2 -GLOB_WORLD_ORIGO_OFFSET_X-SYMB_POS_X, -GLOB_WORLD_ORIGO_OFFSET_X-SYMB_POS_Y
line2 -0.1, 0.0, 0.1, 0.0
LINE2 0.0, -0.1, 0.0, 0.1
hotspot2 0.0, 0.0, 1
text2 0, 0, "( 0.00 ; 0.00 )"
text2 0, 0.5, "World Origin"
del top

if abs(GLOB_WORLD_ORIGO_OFFSET_X) > 0.01 or\
    abs(GLOB_WORLD_ORIGO_OFFSET_Y) > 0.01 then
   ! THIS WILL NEVER BE EXECUTED
    add2 - SYMB_POS_X, - SYMB_POS_Y
    line2 -0.1, 0.0, 0.1, 0.0
    line2 0.0, -0.1, 0.0, 0.1
    hotspot2 0.0, 0.0, 2
    text2 0, 0, "(" + str(GLOB_WORLD_ORIGO_OFFSET_X, 9, 4) + "; " + str(GLOB_WORLD_ORIGO_OFFSET_Y, 9, 4) + " )"
    text2 0, 0.5, "Virtual Origin"
    del top
endif

if abs(GLOB_WORLD_ORIGO_OFFSET_X + SYMB_POS_X) > 0.01 or\
    abs(GLOB_WORLD_ORIGO_OFFSET_Y + SYMB_POS_Y) > 0.01 then
    line2 -0.1, 0.0, 0.1, 0.0
    line2 0.0, -0.1, 0.0, 0.1
    hotspot2 0.0, 0.0, 3
    text2 0, 0, "(" + str(GLOB_WORLD_ORIGO_OFFSET_X + SYMB_POS_X, 9, 4) + "; " + str(GLOB_WORLD_ORIGO_OFFSET_Y + SYMB_POS_Y, 9, 4) + " )"
    text2 0, 0.5, "Object Placement"
endif

I found that ....

if abs(GLOB_WORLD_ORIGO_OFFSET_X) > 0.01 or\
    abs(GLOB_WORLD_ORIGO_OFFSET_Y) > 0.01 then

needs to be ...

if abs(GLOB_WORLD_ORIGO_OFFSET_X) > 0.01 or abs(GLOB_WORLD_ORIGO_OFFSET_Y) > 0.01 then

All on one line and the "/" removed after the OR

I couldn't reproduce that in AC24 build 3022.
This offset is only recalculated when a file is opened, so it might look it isn't working with a moved object.
First move the object far away from the origin, save the file, re-open it, and the extra hotspot will be visible.

THAT was the missing piece of information...
Sorry for the confusion and thanks to Péter!

It becomes quite obvious when you think about it, but man, sometimes the easiest things are the hardest.
