Map making is a key part of making many types of games.

Most maps are created use pre-drawn images on the graph screen, while a select few make use of the home screen. The graph screen is more versatile with its larger size and compatibility. Pxl-test( is often used to keep a character on or within the boundaries of a map.

== Pxl-test( ==

[[TI-BASIC:Pxl_Test|pxl-Test(]] is what the whole programs runs off.
The command pxl-Test( returns either 1 or 0, indicating whether a pixel is activated or not. Using this, you can use a movement loop where the character will not move onto (5,2) If Pxl-Test(5,2)->A. If A=1 then the program will not move onto the spot.

== Code ==

Type in this code into your calculator:

ClrDraw
RecallPic 1
55→X
60→Y
Repeat A=45
Pxl-On(Y,X
Repeat Ans
getKey→A
End
Pxl-Off(Y,X
X-(Ans=24 and not(pxlTest(Y,X-1))+(Ans=26 and not(pxl-Test(Y,X+1→X
Y-(A=25 and not(pxlTest(Y-1,X))+(A=34 and not(pxl-Test(Y+1,X→Y
End

== Instructions ==

Make any random map that pleases you and press [2ND] + [DRAW] + [LEFT] + [ENTER] + [1] + [ENTER] (Storepic 1). This will override Pic1 with whatever map you created. The movement loop will need to be customized for your map though. A simple maze game is easier to make then a platformer that requires jumping, shooting, moving, etc.

== Things to make sure of ==

1) Make sure that the pixel at (55,2) is not activated (black)
2) Make sure that your window settings are as follows: Xmin=0, Xmax=94, Ymin=0, Ymax=62. This makes sure that the resolution on the screen fits the pt-On( command (this makes life easier)
3) Remember that Pxl-On( follows the syntax of Output where it is Pxl-On(Row, Column).[[Category:TI-BASIC]]
