okay i need help for my game im new to turing and dont understand most of what im doing, but heres my program var keys : array char of boolean var piggy : int := Pic.FileNew ("F:/ICE3/Turing/Game/pics/piggy.BMP") var background : int := Pic.FileNew ("F:/ICE3/Turing/Game/pics/background2.BMP") var bulletBill : int := Pic.FileNew ("F:/ICE3/Turing/Game/pics/BulletBill.BMP") var cloud : int := Pic.FileNew ("F:/ICE3/Turing/Game/pics/clouds.BMP") var cloud2 : int := Pic.FileNew ("F:/ICE3/Turing/Game/pics/clouds.BMP") var piggyX : int := 0 var piggyY : int := 0 var backgroundX : int := 0 var backgroundY : int := 0 var bulletBillX : int := 550 var bulletBillY : int := 10 var cloudX : int := 300 var cloudY : int := 250 var cloud2X : int := 150 var cloud2Y : int := 100 setscreen ("offscreenonly") %intructions% locatexy (230, 250) put "Press Enter To Start Playing" locatexy (160, 200) put "To Control The Character Use The Arrow Keys" locatexy (170, 180) put "To Move Out Of The Way Of The Bullet Bill" View.Update Input.Pause cls loop Input.KeyDown (keys) % Character Blue Meanie and movements %Move Character Right Across The Screen if keys (KEY_RIGHT_ARROW) then Pic.Draw (piggy, piggyX, piggyY, picMerge) if piggyX >= maxx then piggyX := -20 end if piggyX := (piggyX + 2) end if %Move Character Left Across The Screen if keys (KEY_LEFT_ARROW) then Pic.Draw (piggy, piggyX, piggyY, picMerge) if piggyX <= -100 then piggyX := maxx + 20 end if piggyX := (piggyX - 2) end if %Move Character Up The Screen if keys (KEY_UP_ARROW) then Pic.Draw (piggy, piggyX, piggyY, picMerge) if piggyY >= maxy then piggyY := -20 end if piggyY := (piggyY + 2) end if % Move Character Down The Screen if keys (KEY_DOWN_ARROW) then Pic.Draw (piggy, piggyX, piggyY, picMerge) if piggyY <= -100 then piggyY := maxx +20 end if piggyY := (piggyY - 2) end if % Move Bullets % Pic.Draw (bulletBill, bulletBillX, bulletBillY, picMerge) bulletBillX := (bulletBillX - 12) if bulletBillX <= -100 then bulletBillX := maxx + 20 end if % Cloud Movement % % Cloud One % Pic.Draw (cloud, cloudX, cloudY, picMerge) cloudX := (cloudX - 5) if cloudX <= -100 then cloudX := maxx + 20 end if % Cloud Two % Pic.Draw (cloud2, cloud2X, cloud2Y, picMerge) cloud2X := (cloud2X - 5) if cloud2X <= -100 then cloud2X := maxx + 20 end if %Draw Background And Characters % Pic.Draw (background, backgroundX, backgroundY, picMerge) Pic.Draw (bulletBill, bulletBillX, bulletBillY, picMerge) Pic.Draw (piggy, piggyX, piggyY, picMerge) Pic.Draw (cloud, cloudX, cloudY, picMerge) Pic.Draw (cloud2, cloud2X, cloud2Y, picMerge) View.Update end loop what i need help with is making the bullet move accros the screen randomly, and also i need to have the game end when the bullet hits the character any help would be awsome, because this is a school project due very soon thanks. |

If you mean making the bullet start in a random location on one side of the screen you can use a randomly generated number between 0 and 1 multiplied by the height of your screen and have the bullet start at that location. As for the program ending when the player gets hit you'll need to use collision detection and end the program when it detects a hit. Useful source code can be found in the missile example game that comes with turing. Hope this helps. |

Instead of taking others code!!! (which is cheating). Why not think of ways to do collision detection and implement it in the code for your program? |
