I also created an enum with my four directions to make things a little more readable. I didn’t mention it, but you can see it here. Within the same loop, I draw a different colored square that represents the food that the snake must eat to grow, with one crucial caveat I need to pay attention to the location of the food must be stored within a variable that I can match to the head of the snake. But I could not use the struct since the struct had not been initialised before the compiler wanted to initialise the variable here.
#Classic snake html code code
Note the code defining the first entry into this array is identical to the snake body struct. A view that needs to remember its position. common).autoconnect()īeyond that, I need a view representing each segment of the snake. var timer = Timer.publish(every: 0.5, on. To start, I need a loop since the snake moves continuously, so a timer like this is the obvious choice. The challenge is that the snake, as it becomes longer, must not hit the sides or itself self a game that gets progressively harder as the snake gets longer, and the case of this implementation gets faster as well. As you eat the singles, the snake absorbs them and becomes just that little bit longer. You must navigate the screen to “eat” single squares that appear randomly on it. The GameĪt its most straightforward, the snake game is nothing more than a square. Join me in this short paper to build your copy of the snake game using pure SwiftUI. Another similar but different game that predated Tetris another classic a more straightforward implementation is the snake game. The other week I published an article about my journey to build the Tetris game a challenge.
