![]() ![]() The check_for_win function works out whether the current game state fulfills either condition. Three instances of the same symbol exist in the same row, column, or diagonal.Keeping track of down lets you identify when the button is first clicked, since stat() just tells you whether the button is down when it runs. In _update, use a global variable to keep track of the state and call stat(34) to check if the left mouse button is down: if ( down and stat ( 34)= 0) then You can keep track of mouse button presses in a similar way to the mouse position. Mouserow=flr((mousey/42.666) % 3) Handling User Input Using the fact that the screen is 128x128, and the grid is 3x3, you can convert x and y coordinates to grid references like this: mousecol=flr(mousex/42.666) You can translate from a column & row reference to an index in this array, and back again. PICO-8 arrays begin at index 1, not index 0 as is typical in many languages. You can access elements of this array using a syntax familiar from other languages. You just need to keep track of nine different locations in the grid: p = While PICO-8 does support multi-dimensional arrays, it’s just as easy to use a one-dimensional array for simple use cases like this. To play a meaningful game, you’ll need a way of tracking which symbol, if any, is in which square. To complete that function, though, you’ll need to access the game state. It draws the symbol (cross or nought) in a given grid square, if there is one. The remaining drawing function is draw_square. You’ll need to draw two intersecting diagonal lines: function draw_cross( x, y) You can use this to display both the current “board” and a “preview” symbol as the user hovers their mouse over an empty square.ĭrawing a “nought” is simply a case of calling the PICO-8 circ() function: function draw_nought( x, y)ĭrawing a “cross” is slightly more complicated. The next task is to draw a symbol-nought or cross-in a given square. Since a PICO-8 screen is 128x128 pixels, each square can be 42 pixels, leaving 1 pixel for the grid lines: You can recreate this using four lines: two horizontal and two vertical. Tic-tac-toe takes place on a grid of nine squares. ![]() Try removing this line to see what happens when you don’t clear the screen. It takes four arguments to draw a line between two points: the x and y coordinates of point a, and the x and y coordinates of point b. The line() function is another that’s built into PICO-8. Line(mousex - 4, mousey, mousex + 4, mousey) Line(mousex, mousey - 4, mousex, mousey + 4) For a crosshair-style pointer, you can draw a vertical line and a horizontal line at the current mouse position: function _draw( ) It gives various details about the current environment, including the mouse, keyboard, and date/time.įinally, define a _draw function to display a pointer on-screen. PICO-8 includes stat as a built-in function. Note that variables in PICO-8 are global by default, so any function in your program will have access to mousex and mousey. To support mouse input, this is the place to keep track of the pointer’s position. If you don't mind paying, it will serve you and your needs well.The _update function handles user input and updates to your game’s state. It's easy to use, highly customizable, and even comes with some nice extra for your keyboard.
