game camera

General
1

I have been searching for a while but can’t find anything, how do you get the camera(in the game) to focus on certain things and is there a way to make the canvas, room, level, or whatever you call it bigger or are you limited to do only what it gives you.

The camera statement has arguments for where the camera is and what it’s looking at. To move the camera to look at different thing, just change the x,y,z values for the look at variables. You can also change how big or small the view is by changing the perspective parameters. Look in the built in reference for the camera information.

@sadnessIsIimited do you mean for 2D or 3D? As @dave1707 says, use camera for 3D, but for 2D, use translate rotate and scale

2D

Thx

So what function would I use that in I’m still having trouble with this
And where would I put translate

I am trying to make this a parameter and then once I make the player I am going to make the camera focus on that

@sadnessIsIimited I copied this from another discussion where I gave this as an example. Is this close to what you’re trying to do. I keep the main character in the center of the screen and the background and other objects get moved around the screen. Also, the playing area is a lot bigger than the screen size.

displayMode(FULLSCREEN)

function setup()  
    spTab={"Platformer Art:Coin","Planet Cute:Key",
            "Small World:Flag","Small World:Heart","SpaceCute:Star"}
    tab={}
    for z=1,100 do
        table.insert(tab,vec3(math.random(-20,20),
                    math.random(-20,20),math.random(5)))       
    end
    dx,dy=0,0
    xval,yval=0,0
end

function draw()
    background(142, 228, 101, 91)
    for a,b in pairs(tab) do
        sprite(spTab[b.z],b.x*100+dx,b.y*100+dy)
    end  
    sprite("Platformer Art:Guy Standing",WIDTH/2+23,HEIGHT/2-20)  
    sprite("Cargo Bot:Command Left",75,HEIGHT/2,50,50)
    sprite("Cargo Bot:Command Left",WIDTH-75,HEIGHT/2,-50,50)
    sprite("Cargo Bot:Command Grab",WIDTH/2,HEIGHT-75,50,-50)
    sprite("Cargo Bot:Command Grab",WIDTH/2,75,50,50)
    dx=dx+xval
    dy=dy+yval
end

function touched(t)
    if t.state==BEGAN then
        if t.x<200 then
            xval=2
        elseif t.x>WIDTH-200 then
            xval=-2
        elseif t.y<200 then
            yval=2
        elseif t.y>HEIGHT-200 then
            yval=-2
        end
    elseif t.state==ENDED then
        xval,yval=0,0
    end
end
