I'm working in a mature project and I'm getting concerned about different screen resolutions and wish to clear this out. I'm working on a scene containing a tk2dCam having a native size of 1280x720.
First off.. what would be the best native res to start off a project?
What would be the best resolution of each texture that I import? Should it be 1:1 with native size? (meaning that if on screen I want a box of 100x100, should I import a 100x100 texture? I'm thinking of importing 200x200 instead and scale it to 0.5, in case if the resolution is larger, the sprite does not get stretched.
And how can I cater for all/most types of resolutions. What would happen to my sprites if the game is played from a 2560x1440 display (X2 native res - just for example) or simply from an HD display, or even at a lower res such as 800X480.
If I create a background of 1280X720 how will it be displayed on larger and smaller resolutions?
Thank you for reading, I'm pretty confused when it comes to build a game to multiple screen sizes and have no more than 1 device to test this on my own.
