Hello

I'm having the "Error in line XX: Not showing" error when trying to hide sprites safely. The error does not happen if I use sprite hide. Maybe it is a possible bug?

The code is running on the MMBasic for Windows V5.07.03

I isolated the code that causes the error.


dim s=1,i,o=20

mode 7,12 ' 320x240

page write 2: cls
load png "km_tileset.png"
page write 0: cls

for i=1 to 6
   sprite read i, 0, 128, 16, 16, 2
next

do
   o=20
   for i=1 to 6
       if s then
           sprite show i, o, 20, 0
       else
           ' sprite hide I <= This one works fine, the next line doesn't
           sprite hide safe i
       end if
       inc o, 20
       pause(500)
   next
   s=not s

   pause(500)
loop


The tiles file:

The bug is there on the CMM2 as well. It appears it only relates to layer 0. If you set the layer to 1 it works OK - now I just need to find out why

sprite show i, o, 20, 1
