2 short questions, BGPUT 2, and DIM L0[0,0]

  • #1 ✎ 9 Jack_Akkiarto Hello, i have 2 short questions: 1.) Why can't i use BGPUT 2,0,0,5 to put a Tile in the second Layer? If i only write this line in a new program, i get an error, but if i replace the 2 with a 1 it works fine for the 1st layer. 2.) If i write DIM L0[0]:PUSH L0,7 ,the push function works fine, but if i use DIM L0[0,0]:PUSH L0[0],7 ,i get an error, can somebody tell me how to use push in a 2-dimensional array? Thanks for every help Posted Edited by Jack_Akkiarto
  • #2 ✎ 477 SquareFingers PUSH only works on one-dimensional arrays (and strings). 2D arrays in SmileBasic are rectangular, not 'jagged', so even in principle, there's no way (in general) to push a single value to a 2D SmileBasic array. I don't know BGPUT, I'll leave that question for someone else. Posted
  • #3 ✎ 9 Jack_Akkiarto Thanks for the fast answer, but can you also tell me if there is a way to make a 2-dimensional array bigger after i created it? Posted

Express Yourself There is no way to resize 2/3/4-dimensional arrays, other than loading from a DAT file. You can't resize a 2/3/4-D array in place, but what you can do is something like: DIM ARRAY[10,10] 'make original array DIM NEW[11,10] 'create new array. You can only easily resize the FIRST index COPY NEW,ARRAY 'copy data to the new array ARRAY=NEW 'replace original array with new array. the BGPUT won't work because you're using XSCREEN mode 2 or 3, which assign BG layers 0 and 1 to the top screen, and 2 and 3 to the bottom screen. You have to use DISPLAY to switch to the lower screen, or you can change the number of layers on the upper screen with optional arguments to XSCREEN. Posted Edited by 12Me21

    If you have activated the bottom screen with XSCREEN, sprite and BG elements were divided amongst the two screens evenly. This means that BG layers 0 & 1 are on the top screen, and 2 & 3 are on the bottom screen. Check the help menu for XSCREEN to solve your issue.
