Touches break Craft?

Questions

So, maybe I’m late to the party on this, but it seems like if I add a touched(touch) function to a Craft project then nothing else in the project detects touches? For instance, the orbitViewer no longer works…

@UberGoober That’s because when you add the touched function in your code, it overrides the touched function in Craft. I have an example somewhere that allows you to do it. I’ll post the example when I find it.

Here’s the example. The important code is the addHandler in the btn1:init function. You can set a priority to your touch. When you touch the green box where the red box is behind it, since the red box has a higher priority, then it registers the touch, not the green box.

viewer.mode=FULLSCREEN

function setup()
    col={{name="red",c=color(255,0,0)},{name="green",c=color(0,255,0)}}
    assert(OrbitViewer, "Please include Cameras (not Camera) as a dependency")
    scene = craft.scene()
    v=scene.camera:add(OrbitViewer, vec3(0,0,0), 100, 0, 200)
    c=scene:entity()
    c.model = craft.model.cube(vec3(25,10,10))
    c.material = craft.material(asset.builtin.Materials.Standard)
    c.material.map = readImage(asset.builtin.Blocks.Trunk_White_Top)
    b1=btn1(300,100,200,150,-2,col[1].name,col[1].c)
    b2=btn1(400,25,200,150,-1,col[2].name,col[2].c)
    str="Press a button or rotate the box"
end

function draw()
    update(DeltaTime)
    scene:draw()  
    fill(255)  
    text("Drag your finger on the screen to rotate the box",WIDTH/2,HEIGHT-100)
    text(str,WIDTH/2,HEIGHT-200)
    b1:draw()
    b2:draw()
end

function update(dt)
    scene:update(dt)
end

btn1 = class()
    
function btn1:init(x,y,w,h,p,n,c)
    self.x=x
    self.y=y
    self.w=w
    self.h=h
    self.name=n
    self.col=c
    touches.addHandler(self,p)     -- register class with priority
end

function btn1:draw()
    fill(self.col)
    rect(self.x,self.y,self.w,self.h)    
end
    
function btn1:touched(t)
    if t.state == BEGAN then
        if t.x>self.x and t.x<self.x+self.w and
                t.y>self.y and t.y<self.y+self.h then
            str=self.name.." button pressed"
            return true
        end
    elseif t.state==ENDED then
        str="Press a button or rotate the box"
    end
end
