I’m developing a copy of the classic Snake game to teach some people the concepts of Xojo.
The game area is Canvas 640480 and the Snake’s dimension are 1616 pixel cubes, so the snake fits exactly 40 times in the play area.
The cookie/coin/food (whatever it is that the snake eats) is also a 16*16 cube. I’m trying to figure out how to place the snake and cookie aligned to each other so that the snake’s path/trajectory fits exactly to the alignment of the cookie.
To place a cookie I use the following code:
Const PLAYFIELD_WIDTH = 640
Const PLAYFIELD_HEIGHT = 480
Const SNAKEUNIT = 16
'Randomize Dim r As New Random 'ranges for x and y Dim FoodX As Integer = r.InRange(0,PLAYFIELD_WIDTH-(SNAKEUNIT/2)) Dim FoodY As Integer = r.InRange(0, PLAYFIELD_HEIGHT-(SNAKEUNIT/2)) 'correct x and y values to fit into the matrix FoodX = FoodX-(FoodX mod 16) - (SNAKEUNIT/2) FoodY = FoodY-(FoodY mod 16) - (SNAKEUNIT/2)[/code]
So the X and Y are random and I have to correct them.
But cookie and snake do not align to each other. I use the same code a s a starting point for the snake. What is wrong here?
