Stick direction?

dmoeller

I am trying to make the stick figure go in the direction that is the difference from where I fist touched and where my finger is moving now
This is what I have, any help would be appreciated

-- Stick

-- Use this function to perform your initial setup
function setup()
    angH = 0
    time = 0
    motion = "standing"
    stickx = 100
    sticky = 100
    speed = 0
end
function touched(touch)
    if touch.state == BEGAN then
        startx = touch.x
        starty = touch.y
    elseif touch.state == MOVING then
        angH=angH-(touch.deltaX)%360
        speed=(touch.y-starty)/250
        if speed > 1 then
            speed = 1
        elseif speed < -1 then
            speed = -1
        end
    elseif touch.state == ENDED then
        speed= 0
    end
end
-- This function gets called once every frame
function draw()

    background(255, 255, 255, 255)
    time = time + 1
    -- This sets the line thickness
    strokeWidth(5)
    x=speed*math.sin(math.rad(angH))
    y=speed*math.cos(math.rad(angH))
    if time > 30 then
        if motion == "standing" then
            motion = "walking"
        else
            motion = "standing"
        end
        time=0
    end
    stickx = stickx + x
    sticky = sticky + y
    if motion == "standing" then
        sprite("Documents:stand",stickx,sticky,40,100)
    else
        sprite("Documents:walk",stickx,sticky,40,100)
    end

    -- Do your drawing here

end

If all you want is the stick figure to go towards your finger, this will work. Just a suggestion. If you use sprites other than those that come with Codea, other users can’t see or use them. We can’t see your Documents walk or stand sprites. For me, I just see a black rectangle. If you’re going to post code with sprites, replace your sprites with some close Codea sprites just so we see something.

function setup()
    time = 0
    motion = "standing"
    stickx = 100
    sticky = 100
    mx,my=stickx,sticky
end

function touched(t)
    if t.state==MOVING then
        mx,my=t.x,t.y
    end
end

function draw()
    background(255, 255, 255, 255)
    time = time + 1
    if time > 30 then
        if motion == "standing" then
            motion = "walking"
        else
            motion = "standing"
        end
        time=0
    end
    stickx = stickx - (stickx-mx)/25
    sticky = sticky - (sticky-my)/25
    if motion == "standing" then
        sprite("Documents:stand",stickx,sticky,40,100)
    else
        sprite("Documents:walk",stickx,sticky,40,100)
    end
end

How would you make it with a joystick?

Here’s something I had.

displayMode(FULLSCREEN)

function setup()
    inner=80    -- size of inner circle
    outer=200   -- size of outer circle
    diff=outer/2-inner/2
    sx,sy=WIDTH/2,HEIGHT/2
end

function draw()
    background(40, 40, 50)
    sprite("Planet Cute:Character Horn Girl",sx,sy)
    js()
end

function js()
    if show then
        v1=vec2(cx,cy)
        d=v1:dist(vec2(x,y))
        if d<diff then
            px,py=x,y
        else
            a=diff/d
            px=(x-cx)*a+cx
            py=(y-cy)*a+cy
        end
        stroke(255)
        strokeWidth(4)
        noFill()
        ellipse(cx,cy,outer)
        fill(255)
        ellipse(px,py,inner)        
        v1=vec2(px,py)
        d1=v1:dist(vec2(cx,cy))
        sp=d1/4+1          
        sx=sx+(px-cx)/sp
        sy=sy+(py-cy)/sp
    end
end

function touched(t)
    if t.state==BEGAN then
        cx,cy=t.x,t.y
        x,y=cx,cy
        show=true
    end
    if t.state==MOVING then
        x,y=t.x,t.y
    end
    if t.state==ENDED then
        show=false
    end
end

This is exactly what I wanted thanks
