Trying to make worm/gravity game

[anywho_ya]

Hey there i was trying to do a game for an isu in school, but so far its crap. 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

code:

View.Set("offscreenonly") var mx, my, b : int var x, y : int x := round(maxx/2) y:=maxy loop     Mouse.Where (mx, my, b)     if b = 1 then         y += 5     else         y -= 5     end if     cls     Draw.FillOval (x, y, 5, 5, red)     View.Update     if y < 0 then         y := 0     end if     if y > maxy then         y := maxy     end if end loop

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

jeeze tony, add a delay
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

Ya i pretty much get the gravity part of it, but the only thing i need is to like get the game to scroll past or sumthing like that ... and i aslo need bricks to move with the worm

thanks with the help so far though

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.

hey, can somebody explain to me what it means when you do x += y

what the heck is += ?

By the way, nice gravity.

[jonos]

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.

sounds reasonable, thanks alot.
