Hello, How would you set speeds to 2 different objects? I am trying to make a user-controlled circle animation go faster than another randomly moving circle animation, but the delay function applies to all above it. Also, how would I set limits to the x-and-y-coordinates of my circles to prevent them from going off the page? I am using Turing 4.1.1. The code is below. Thanks var x, y : int x := 100 y := 100 var obstx, obsty : int obstx := 200 obsty := 100 var obstx2, obsty2 : int obstx2 := 245 obsty2 := 295 var chars: array char of boolean loop Input.KeyDown (chars) if chars (KEY_UP_ARROW) then y := y + 2 end if if chars (KEY_RIGHT_ARROW) then x := x + 2 end if if chars (KEY_LEFT_ARROW) then x := x - 2 end if if chars (KEY_DOWN_ARROW) then y := y - 2 end if cls drawfilloval (x, y, 10, 10, blue) drawfilloval (obstx, obsty, 20, 20, red) drawfilloval (obstx2, obsty2, 20, 20, red) obstx := obstx + Rand.Int (-10, 10) obsty := obsty + Rand.Int (-10, 10) obstx2 := obstx2 + Rand.Int (-10, 10) obsty2 := obsty2 + Rand.Int (-10, 10) if x >= obstx - 20 & x <= obstx + 20 & y >= obsty2 - 20 & y <= obsty2 + 20 then put "Game Over!" exit end if if x >= obstx - 20 & x <= obstx + 20 & y >= obsty - 20 & y <= obsty + 20 then put "Game Over!" exit end if end loop |

How about instead of changing the delay, you change the number of pixels you move per delay? |

How would I do that? And also how would I stop the circles from going off the screen? |

Instead of moving 2 pixels at a time, do 4 pixels at a time. Now your circle moves twice as fast. Can you think of a way to check if the circle is at the edge of the screen? |
