Description

  1. Get Bob appears to get the Bob starting at the wrong origin. (offset by 1 pixel x and y)
  2. Get Bob appears to get the Bob in the wrong size. (appears to be about 3 pixels off x and y)
  3. In Amiga mode, Get Bob is getting an anti-aliased image, but shouldn't be. (Bob should look identical to original.)
  4. Bob appears to draw the bob in the wrong place offset down and right by 1 px. (Is it possible that the Hot Spot origin is off too?)

Similar problems exist in BOTH Amiga and AOZ modes. (See example below)

#manifest: "amiga"
#splashScreen:false
/*
    Bob size & origin issue (RC3)
    Bob also may be placing the Bob offset by 1 pixel X & Y.
    In Amiga mode, Get Bob is anti-aliased.
    (I scaled the display up to make it easier to see the problems.)

    The same problem exists in AOZ moe.

While testing, you may also want to change the scale to bigger than 5,5 (maybe try 16,16) to more easily see the issues.

Actions #3

  • Assignee changed from Francois Lionet to AOZ Developers
  • Estimated time changed from 2:00 h to 8:00 h
  • Affected version changed from Beta RC3 to 1.0.0 (B7)

Get Bob is offset in 1.0.0 (B7).

Cls 0
For BobNum=1 To 6
  Ink BobNum+1 : Box 1,1 To 10,10
  Get Bob BobNum,1,1 To 11,11
Next BobNum
Cls 0

x = 10 : y = 10
For BobNum=1 To 6
  Bob BobNum,x + BobNum*20, y,BobNum
Next BobNum

The above example will miss the left and top pixels of the object.
If I change the Get Bob to start a 0,0 then the whole object will be grabbed.
