This function will emulate the 7 segment LCD display as found on calculators and other electronic devices.
You could use this for any number of things, but what I had in mind was score displays in futuristic styled games.

drawdigit(X position, Y position, Number to display, Digits in display, RGB colour value)

Run the example to get the idea. If there are less digits in the 'number to display' than specified in the 'digits to display' then the gaps will be filled in with zeros.

That looks surprisingly awesome. Reminds me of the gun counters in Aliens etc.

I made one with thickness a while ago, but it's much slower than yours:

electro_digit3(8,8,x,4)

inc x
Loop

function electro_digit(Xpos as integer, Ypos as integer, L1 as boolean, L2 as boolean, L3 as boolean, L4 as boolean, L5 as boolean, L6 as boolean, L7 as boolean)

XPos=XPos+4
YPos=YPos+4

For y = -2 to 2
For x = 2+ABS(y) to 30-ABS(y)

If L1 then DOT x+0+Xpos,y+0+Ypos
If L2 then DOT y+0+Xpos,x+0+Ypos
If L3 then DOT y+32+Xpos,x+0+Ypos
If L4 then DOT x+0+Xpos,y+32+Ypos
If L5 then DOT y+0+Xpos,x+32+Ypos
If L6 then DOT y+32+Xpos,x+32+Ypos
If L7 then DOT x+0+Xpos,y+64+Ypos

Next x
Next y

endfunction

function electro_digit2(X as integer, Y as integer, digit as integer)

If digit=1 then electro_digit(X,Y,0,0,1,0,0,1,0)

If digit=9 then electro_digit(X,Y,1,1,1,1,0,1,1)
If digit=0 then electro_digit(X,Y,1,1,1,0,1,1,1)

endfunction

function electro_digit3(X as integer, Y as integer, digits as integer, length as integer)

digits$=STR$(digits)

For z = 1 to length

a$=a$+"0"

Next z

digits$=a$+digits$

True, looks quite good. However, you should use box instead of line to draw the lines (they all seem to be vertical or horizontal) due to its higher speed. At least for me the box-command runs as fast as pase image or paste sprite, line on the other hand is quite slow.

Wow that's really nice

! I made Mr. Kohlenstoff's sugguested change and it looks a tad different... But now one can change thickness.

Using BOX you can just create rectangles, whereas the segments are not rectangles (they taper to a point on each side)
