How do I do these cool things?

[Robin]

That was my plan! I had some great ideas...

Too late.

I will create a superior version!

Try it!

lol my topic got hijacked. Umm, I didn't really catch how to change camera size, after declaring the table (camera = {} ) how do I change it with this? http://love2d.org/wiki/love.graphics.translate

?

You mean scaling?

This is an example that makes everything twice as big, “zooming in” on the center:

Code: Select all

function love.draw()
    love.graphics.translate(-love.graphics.getWidth()/2, -love.graphics.getHeight()/2)
    love.graphics.scale(2, 2)
    love.graphics.translate(love.graphics.getWidth()/2, love.graphics.getHeight()/2)
    ... code here ...
end

It is very unoptimal, but it is just an example.

Interesting, but how can one just make the camera alone change size?

I do not understand your question. What do you want to do exactly? Perhaps it would help if you explained what the player should see.

It's so basic, how can I change the scale of the camera?

If the camera gets big, what you see gets small, and vice versa. http://bryanheisey.com/blog/?p=1

That's exactly what they've been talking about. The "camera" is just an abstract idea of what is being displayed in the viewport. What you do when you zoom in is to simply make everything bigger, so that not everything fits in the viewport. Zooming out is making everything smaller, so that you can see more stuff in the viewport.

To be more exact, it works like this:

Code: Select all

camerasize = screensize / scale

(not actual code )
