Working with resolutions (also some bug with click_and_drag if used with custom render script)

Questions
#1

Is there a way to make my game displayed pixel perfect? It may be critical if game has pixel art graphics. Tried some render samples and it seems that’s not what I am looking for. My initial resolution is 240x320, so I need only proportional scaling x2. I.e. 480x640, 640x980, 720x960, 960x1280 depending on game window size. I know already that working with resolutions in Defold is not that simple, so is this actually possible?

@britzl There is also some bug with cursor in this script if used with custrom render scripts. Is there a way to fix it?

You can try flappy bird game example. It is pixel, and contains complicated logic for scaling. If you need only proportional scaling , you should check aspect ration of screen, and then add some border in x or y, if aspect of screen is different then your. https://github.com/d954mas/defold-flappy-bird/blob/master/lib/screen_helper.lua

Thank you. Your approach is really nice, results are predictable. But, actually, scaling works only in Defold redactor (windows and android builds also works well, I think macOS versions will be ok too). But HTML5 build doesn’t scale in browser :frowning: Hm… Seems that HTML5 build doesn’t support scaling of game window regardless of the render script.

You can change width and height in game project. =)

If you use a custom render script you need to translate screen coordinates to proper world coordinates. I’ve solved this in a generic way in my Orthographic Camera API where you can do camera.screen_to_world() and vice-versa. The provided render script also has multiple configurations for pixel perfect scaling.

Thank you britzl for your help. This extension It is really useful, as always. Without this and other extensions it would be really painful to use Defold for non-programmers such as me. :slight_smile:
