Multiple resolutions - solid example

This should be sticky, I wish I'd seen it before..

Why are you setting this: "(LayoutHeight * scaleRatio - WindowHeight) / 2 / scaleRatio" technically the result would always be 0? Or am I missing something?

I tried to put it in my game prototype and used rex's debugpanel and I also get the values as 0

All my objects seem resized to same and centered on the screen.

Not sure what I'm missing. <img src="smileys/smiley18.gif" border="0" align="middle" />

Guess this is what happens if you blindly follow an example.

I am trying to get my player and objects to scale.

So wondering if the right way is to set player position to (currentXposition*scaleRatio, currentYposition*scaleRatio) and setting size to (currentXsize*scaleRatio, currentYsize*scaleRatio)

Anyone?

Hi gammabeam,

The link is showing an "Error (404)"

someone has to share the file again. The link is broken

oops, sorry guys. I went through my dropbox folder and now it's gone.

I'll try to find it and post it again!

ugh, it's gone... can someone send me the file so I can put it back online? <img src="smileys/smiley19.gif" border="0" align="middle" />

Here you go gammabeam <img src="smileys/smiley1.gif" border="0" align="middle">

Multiple resolutions - solid example.capx

I knew I had it some place in my disorganized 365GB's of files. lol

I reopen this topic asking — or others for help.

Taking your example how can I programmaticaly put an element on the bottom of the screen consistently across different ratios?

Take this example:

I want an element to be exactly his height from the bottom of screen (origin center), x is irrelevant:

At the beginning I was doing this:

(WindowHeight / scaleRatio) - (sprite.Height/2)

Which worked on the normal ratio but started doing strange things with different ratios, it became apparent that that H would change with the ratio, so I did a proportion:

(WindowHeight / scaleRatio) - ( ((sprite.Height* (WindowHeight / scaleRatio))/LayoutHeight) / 2 )

But doesn't work, why?

Here is a modified capx showcasing my problem: capx, how can I make the "start" button stick in the same position (bottom of screen - self.Height) across different resolutions?

Thanks for any help

Anyone?

I'm not sure about the math, bust at a glance, use viewportbottom instead. Windowheight grabs the height of the whole window, rather than just the windows's content.

I may have stumbled onto a bug?

After banging my head onto a wall I discovered that for some strange reason viewportbottom/top change value during execution, it looks like it needs to stabilize..

If you execute it "on start" it returns a value, if you execute it "every tick" it gives a different value (the first is the same as onload) all the subsequent are the correct ones.

Why?

Ahh, that might explain the weird behavior I've been having with my ui. At a guess, it might have something to do with the canvas being resized to full screen at start and so returning a value from before the resize? Not sure exactly...

I've been getting around it by running the ui placement code for a few ticks before deactivating the group.

I ended up creating two global variables that gets populated with viewportBottom/top after an event on the main menu, because I needed it at the very beginning of the "game" layout.

Oh duh, yeah, that's a better idea. :)

Help me, do not know what resolution is best for my all generation iphones and ipads. Should i draw a different size images and to load them depending on what phone&ipad do i use?, and how to do it? or draw is always high resolution and scale it up?
