Its supposed to look like this game http://www.addictinggames.com/worm.html but it doesnt work properly. I would add the code i have so far but i left it at school. It'd be great if you could help me out. Thanks

making gravity is not difficult.
you have an x and y position of your worm. you also have a vx and vy values for your worm. these values are the x and y velocities of the worm. to make gravity, just make the dy value decrease by a certain amount each time the loop executes.

EXAMPLE CODE
 code: setscreen ("offscreenonly") var x, y : real var vx, vy : real x := 0 y := 100 vx := 1 vy := 3 loop     x += vx     y += vy     vy -= 0.015     exit when y < -10     cls     drawfilloval (round (x), round (y), 5, 5, black)     View.Update     delay (10) end loop

anywho, to add gravity to tony's code...

 code: setscreen ("offscreenonly") var x, y : real var vx, vy : real x := 100 y := 100 vx := 0 vy := 3 var mx, my, mb : int const gravity := 0.02 loop     Mouse.Where (mx, my, mb)     x += vx     y += vy     vy -= gravity     if mb = 1 then         vy += 0.2     end if     cls     drawfilloval (round (x), round (y), 5, 5, black)     View.Update     delay (10)     exit when y < -10 end loop

 Author: Cervantes [ Tue May 04, 2004 3:42 pm ] Post subject: well you need to randomly generate a maze that the player tries to get through. Bunch of ways to do that im sure. Then, once you've done that, every time through the loop move each object in the maze to the left (or right, but its left in the worms game on addictinggames.com). then check for a collision. shouldn't be that difficult.

 Author: jonos [ Wed May 19, 2004 10:32 pm ] Post subject: It's just short for x = x+y ex: x += 1 is x = x+1 x -= 1 is x = x-1 and there you have it. I'm probably wrong though.
