When i use my joystick i get stick in the corners on the joystick. Does anyone have a solution to this problem? It would also be nice if someone could give me a good/simple solution to make the character stay inside the bounds of the screen.
-- Joystick
Joystick = class()
function Joystick:init(x,y)
self.initial = vec2(x,y)
self.c = vec2(x,y)
self.circle = vec2(x,y)
self.sensitivity = 10 -- sensitivity
end
function Joystick:draw()
self.deltaX,self.deltaY = self.circle.x-self.initial.x,self.circle.y-self.initial.y
spritePos.x = spritePos.x + self.deltaX/self.sensitivity
spritePos.y = spritePos.y + self.deltaY/self.sensitivity
pushStyle()
fill(89, 89, 99, 100)
rectMode(CENTER)
ellipse(self.c.x,self.c.y,200)
fill(103, 111, 119, 255)
ellipse(self.circle.x,self.circle.y,50)
popStyle()
end
function Joystick:touched(touch)
t = vec2(touch.x,touch.y)
if t:dist(self.circle)<30 then
self.circle = vec2(t.x,t.y)
end
if self.circle.x>self.c.x+100 then
self.circle.x=self.c.x+100
end
if self.circle.x<self.c.x-100 then
self.circle.x=self.c.x-100
end
if self.circle.y>self.c.y+50 then
self.circle.y=self.c.y+50
end
if self.circle.y<self.c.y-50 then
self.circle.y=self.c.y-50
end
if touch.state==ENDED then
self.circle = self.initial
end
end
--# Main
-- Joystick
displayMode(FULLSCREEN)
function setup()
spritePos = vec2(WIDTH/2,HEIGHT/2)
jstick = Joystick(150,150)
end
function draw()
background(40, 40, 50)
jstick:draw()
sprite("Planet Cute:Character Boy",spritePos.x,spritePos.y)
end
function touched(touch)
jstick:touched(touch)
end
Okej Thanks @Ignatz if you try to drag the joystick to the corner and if you drag your joystick directly from the corner to some of the sides besides the corner it will often get stuck, do you understand the problem? If you do, do you have any solution for it? Because you can only move the joystick In a rectangle but I want it to move in a circle so it don’t get stuck in the rectangle corners.
@llEmill - Use this code for your touched function
function Joystick:touched(touch)
t = vec2(touch.x,touch.y)
local d=t:dist(self.c)
if d<75 then self.circle=t
else self.circle=self.c+(t-self.c):normalize()*75 end
if touch.state==ENDED then self.circle = self.initial end
end
@Ignatz one last question, sorry for bothering you. How do I do if I only want to move the character when I drag my finger inside the joystick circle? Because now
the character move where ever I tusch on the screen and move at that direction, I will only move him when I have the finger inside the joystick ring. Thanks for your help so far
@Ignatz do you know how to do, to make so the character only move when I tuch inside the joystick and not anywhere on the screen? I need this so I can make more buttons on the screen. It would be very nice if you could help me
@llEmill - It’s important you try to learn how these things are done, so have a look at this, where I used this example to explain how the solution works - and i made it a bit simpler as well.
