So I am new to turing and I'm challenging myself to make a tron lightcycle styled game. Here's what I have so far... %Variables var x, y : int := 10 var x2, y2 : int := 490 var char1 : array char of boolean %Sets window size View.Set ("graphics: 500;500") %Starts the game loop %move with arrow keys Input.KeyDown (char1) if char1 (KEY_UP_ARROW) then y := y + 10 elsif char1 (KEY_RIGHT_ARROW) then x := x + 10 elsif char1 (KEY_LEFT_ARROW) then x := x - 10 elsif char1 (KEY_DOWN_ARROW) then y := y - 10 end if %move with "w" "a" "s" "d" if char1 ('w') then y2 := y2 + 10 elsif char1 ('d') then x2 := x2 + 10 elsif char1 ('a') then x2 := x2 - 10 elsif char1 ('s') then y2 := y2 - 10 end if %set boundaries if x < 0 then x := 0 elsif x > 500 then x := 500 elsif y < 0 then y := 0 elsif y > 500 then y := 500 end if if x2 < 0 then x2 := 0 elsif x2 > 500 then x2 := 500 elsif y2 < 0 then y2 := 0 elsif y2 > 500 then y2 := 500 end if %the thing you move Draw.FillOval (x, y, 5, 5, red) Draw.FillOval (x2, y2, 5, 5, blue) delay (50) %Collision Detection if x = x2 and y = y2 then exit elsif x = 0 or x = 500 then exit elsif y = 0 or y = 500 then exit elsif x2 = 0 or x2 = 500 then exit elsif y2 = 0 or y2 = 500 then exit end if end loop If you play it, it does run. There are two things I would like to do: 1) Make it so the characters move on their own in a direction by themselves until direction is changed by user input 2) Make it so if the characters hit any dot/wall created by either character, the game ends I would love for this game to work. Making something like this would boost my programming confidence. So, how can I make those two things possible? |

Can you make your characters move in one direction, and one direction only, no matter what (don't worry about key presses or changing direction yet). This should be trivial. Just write some code that makes something move infinitely to the right and off the screen. That was easy, you were just adding 1 or 5 or 10 to the X value (depending on how fast you want to move). Wanna make it go to the right? Just subtract from the X value. That 1 or 5 or 10 that you were adding to X is an integer. You know what's nice about integers? You can make a variable out of them! Make an int named 'direction' or something and set it to 1 or 5 or 10 or whatever, and add that variable to X instead of a straight number. Now you can write some code that uses your arrow keys to change the direction variable, and we're done! Remember, if x is positive, your character moves right. If it's negative, your character moves left. Easy! Doing it for the Y axis is just as easy, but you can figure that out yourself. |
