PostPosted: Tue Feb 22, 2005 3:54 pm   Post subject: Slowing Movement with custom-made Joystick

When then joystick moves, the block moves with it, as you can see. However, the movement of the block is too fast. How can i slow it down without adding a delay. (What i tried to do was divide the bottom line by 2, but then it wouldn't be an integer value so it shows an error).

code:

setscreen ("offscreenonly")
var x, y : int := 200
var q, r : int := 400
r := 200
proc draw
    drawfilloval (x, y, 30, 30, 12)
end draw
proc erase
    drawfilloval (x, y, 30, 30, white)
end erase
loop
    drawline (200, 200, x, y, white)
    var a, b, press : int
    mousewhere (a, b, press)
    if whatdotcolor (a, b) = 12 and press = 1 then
        if a < 300 and a > 100 and b > 100 and b < 300 then
            x := a
            y := b
        end if
    elsif press not= 1 then
        x := 200
        y := 200
    end if
    cls
    if press = 1 then
        q := q + (a - 200)
        r := r + (b - 200)
    end if
    delay (100)
    drawline (200, 200, x, y, black)
    drawbox (q, r, q + 100, r + 100, black)
    draw
    View.Update
end loop

Make a lot of calculation commands or something in a process and fork it a bunch of times.

code:

var num : int := 1
process lag
     loop
          num := num + num + num + num
          num := 1
          num := num + num + num + num
          num := 1
          num := num + num + num + num
          num := 1
     end loop
end lag
fork lag
fork lag
fork lag
fork lag
fork lag
fork lag
fork lag


Something to that degree.

i would just put a delay in it because forks are bad and i suggest not to use them.

You are trying to slow down the program without Delay..The only reason not to use a fork is because it slows down your program, are ugly, and go at different times. All of those dont really matter for what he is doing..

If i add a delay, then it becomes really laggy, and the movement isn't smooth. Also, it is VERY bad to add a lot of delay when using mousewhere because the drawing of the circle will be delayed. Confused Anything else? (P.S. can you explain to me the fork method)

Well if you make a process and then fork it it will slow down your program. The more things in the process the slower it will be. Given its not the best method it works best with a loop. I prefer to use delay but if you dont want to just have a lot of forks.

Alright, thanks. I was just wondering if it was possible to set something at decimal coordinates e.g. drawbox (50.5, 30.5, 100, 100, black). If it's possible then plz do tell

Nope its not possible. You can't have somethign on Half a pixel Razz

I made a new version of the program using fork, however, utilizing fork in the way that it is is no different from using delay. GRRRRR Confused , there has got to be another way?!!!!!???

Use a cooldown. That would probably work, talk to "Cervantes" on how to do cooldown, im not entirely sure how to do such a thing yet. Hopefully he won't hate meh for telling people to ask him for help and askign for help myself lolz.

change this part:
code:
if press = 1 then
        q += round((x-200)/2)
        r += round((y-200)/2)
    end if
thats basically the distance from the starting points of the joystick to the new position divided by 2 (and rounded to make it an int) that way more lean stick in one direction faster will go

Wow!! Thanks man, that's good stuff. Well just to show you what the final code of the joystick movement is. I was wondering if you guys can give me an idea of how to apply it to some sort of game, because that would be awesome. I was thinking of some sort of "moving background game".


P.S. Yes, I've already looked at the game ideas section, but most of them don't really apply to this and I want something original. It would be of great help, if you could offer your suggestions Very Happy

Mabey try a ship game of some sort? I never use a joystick so I can't really help you there Razz

Another idea.. you could do a target practice type game, and you move around with the joystick and shoot the targets by pressing the buttons? Idea

I will do both, trust me. I'll give you the end result when i'm done Wink ! Keep these ideas comming, i'm liking this!!!
