CALL_MULTICOLORCHARLOAD()

Description

Like CHARLOAD, this function offers an alternate method of creating custom MULTICOLOR characters and graphics. When this function is called, it will look inside the program for a label named _MULTICOLOR: followed by data statements in a specific format. The first data statement is the character's ASCII code being customized. The next 8 data statements or elements contain the characters hexadecimal color bits.

_MULTICOLOR:
` GUY custom character
data 128             ` ASCII code
data "00BBB000"      
data "00991900"      
data "00999000"      
data "00090000"      
data "0FFFFF00"      
data "F0FFF0F0"      
data "90FFF090"      
data "0CC0CC00"

Each individual character within the data statements line represents a color bit in hexadecimal notation:

Colors Table:

Color Number	Bit Color
0	Transparent*
1	Black
2	Medium Green
3	Light Green
4	Dark Blue
5	Light Blue
6	Dark Red
7	Cyan
8	Medium Red
9	Light Red
A	Dark Yellow
B	Light Yellow
C	Dark Green
D	Magenta
E	Gray
F	White

* A transparent bit will show the current screen color through. Characters will turn invisible if all their bits are transparent.

Example Code

randomize hitimer()
CALL_MULTICOLORCHARLOAD()   ` Loads GUY custom character ASCII 128
for i = 1 to 12
   call_sprite(i,128,0,96,1 + 16 * (i - 1),0,rnd(3)+1)
next i     
display_at(1,1,"Hit any key to magnify",0) 
tiwaitkey()
call_magnify(2) 
call_clear()
display_at(24,1,"Hit any key to end",0) 
tiwaitkey()
END

Note:For this example, copy and paste the following data statements below the _MULTICOLOR: label in the program. Make sure that the last data statement is a single 0 (zero).

` GUY custom character
data 128             ` ASCII code
data "00BBB000"      
data "00991900"      
data "00999000"      
data "00090000"      
data "0FFFFF00"      
data "F0FFF0F0"      
data "90FFF090"      
data "0CC0CC00"     
data 0
