PostPosted: Fri Jan 16, 2004 3:34 pm   Post subject: Help on Metal Gear Solid style game

i am new to turing and i want to make a game like the radar on the Metal Gear games, (I thought it would be easy). For anyone who knows what i am talking about, i wanted to do something like the VR missions, where you have to get to the goal without being seen. My characters are little circles and i finally got them to move. I was wondering if i could get help making larger somewhat transparent cirles over the enemies so that if I go into that range i will get caught by the enemy?

ps- what are bits, what are they for??

you could draw semi-transparent circles using RGB. module, but my guess is that resulting speed will make the game unplayable

i put yellow circles under them instead of semi-transparent ones over them.

Make a picture in paint, then make half of the pixels white (do it in a checkerboard pattern). Then draw the picture using picMerge and it'll be as semi-transparent as you can get it using Turing whilst keeping a decent speed.

i bivle the new turing 4.0.5 will/dose have new opttions for transparcenys in pictuchers.

i need help again, i want to make it so my character (a filled in circle) cant pass through walls.

More Help.......... is there anyway i can declare my circle so that i can use it in an if statement??, or its coords?


for example:
if CIRCLECOORDS= x,y,x2,y2= whatever then
cls
put"you got caught"

As far as I know, the commands are just to set which colour in the picture will be transparent... which if I'm not mistaken was already possible. Razz

jedi-bob, use the force... no, wait, use the coords (and the radius). Compare the distance from the centre of your circle to some point with the radius of the circle, and if the radius is greater or equal, they've collided. In the most recent update to turing, they've actually made a note of explain collision detection. And in case you don't have the latest version of turing, here's the source: (I sure hope holtsoft won't be so petty as to get upset about sharing example code)
code:

% The "Math.Distance" program.
const RADIUS := 75
loop
    var x1, y1, x2, y2 : int
    x1 := Rand.Int (RADIUS, maxx - RADIUS)
    y1 := Rand.Int (RADIUS, maxy - RADIUS)
    x2 := Rand.Int (RADIUS, maxx - RADIUS)
    y2 := Rand.Int (RADIUS, maxy - RADIUS)
    cls
    drawfilloval (x1, y1, RADIUS, RADIUS, brightred)
    drawfilloval (x2, y2, RADIUS, RADIUS, brightgreen)
    locate (1, 1)
    if Math.Distance (x1, y1, x2, y2) < RADIUS * 2 then
        put "The two circles touch"
    else
        put "The two circles do not touch"
    end if
    delay (2000)
    exit when hasch
end loop

thanks, but one problem it says Distance isn't in the export list of Math

Right... I'm stupid. I posted code from turing 4.0.5 in case you didn't have 4.0.5 without realizing that if you don't have 4.0.5, the code wouldn't work. Meh.
I suppose you could just change the Math.Distance to:
code:

round (sqrt ((x2-x1)**2 + (y2-y1)**2))

Or something like that, it's too cold now to think...
