Author Topic: How to check if a box has been completed? (Read 2827 times)

Cobalt · « **on:** November 12, 2021, 01:25:37 pm »

So thanks to some help, the seeker no longer gets stuck. and I have implemented collision between seeker and gapper.
now anybody have a thought on how I should go about checking for completed boxes?
I thought about using an array and check the status of the lines with point.
something like

Code: QB64: [Select]

 SUB Check_Box
DIM Grid_Check(7, 6) AS _BYTE 'largest board(8) is 8x7(0-7,0-6)
  SELECT CASE G.Level
   CASE 1 '3x3(0-2,0-2)
    'check horizontals
    FOR Iy%% = 0 TO 2
     FOR Ix%% = 0 TO 2 'check top line
      FOR x%% = 0 TO 60 STEP 6 'check 10 points
       IF POINT(4 + x%% + 60 * Ix%%, 10) = Magenta THEN full%% = TRUE ELSE full%% = FALSE: x%% = 66
      NEXT x%%
      IF full%% THEN Grid_Check(Ix%%, Iy%%) = TRUE
     NEXT Ix%%
    NEXT Iy%%
    'check verticals
 END SELECT
END SUB
 

The more I look at that, the more it seems like its not going to work as I intend. I gave some thought to using a UDT with UP,DOWN,LEFT,RIGHT to store the completion status of each box, but didn't like the thought of having so much overlap and double checks going on all the time.

I would really appreciate any input on possible methods to for completed boxes.

progress so far:

Code: QB64: [Select]

Follow the directions in the Title bar to test the demo I have for finding surrounded boxes. This requires not just the function BoxSurrounded%(boxNumber) which returns 0 or -1, but an integrated environment to make the function work easily.

Once a box is determined to be surrounded, it never needs to be checked again by checking all Points around it.

EDIT: Sorry, as soon as I posted this I realized a couple of variable names might be confusing and so I substituted better choices, I hope.

Easy to change levels on this code:

Code: QB64: [Select]

_Title "Box Surrounded Test" ' b+ 2021-11-12
 
Screen _NewImage(800, 600, 32) '
_Delay .25
_ScreenMove _Middle
Dim Shared cellsDown, cellsAcross, nCells, cellWidth, cellHeight, surroundColor As _Unsigned Long
 
 
' piece of cake to modify this code for different levels just change these 2 lines!!!
cellsAcross = 10
cellsDown = 8
' ====================================================================================

in this line

row = INT((boxNumber - 1) / cellsPerCpl)

what is cellsPerCpl? its not used anywhere else and has a value of 0 as far as I can tell.

Wow! I missed that typo. It's supposed to be cellsAcross. Like it is in the fillBox routine and the SurroundBox% routine. I wonder why it's not causing problems in my runs of the program, everything works with that crazy typo!?

Originally I had variable cellsPerRow and cellsPerCol which I changed to cellsAcross and cellsDown because I thought that was better wording. cellsPerCpl is a typo p instead of o, so it didn't get changed when I changed the other variable names.

Well now I've a mystery, that typo should cause problems!

Yes, I fixed the typo and a host of errors popped up. I should have them all fixed now here:
