I feel like what I'm currently doing is stupid but would just like reaffirmation it is. Basically I'm writing games which target a certain screen resolution (800x480), so all positions, widths and heights I set for sprites is for that resolution.
On the engine side I have special scalers which will change the width and height of what is being drawn to meet the current platforms res, so for example if the platforms screen res is 1200x720 I will stretch a sprite by a factor of:
1280 / 800.0f; 720 / 480.0f;
Positions are also offset and manipulated in a similar way.
I really feel I should move to a normalized system for widths and positions (i.e. 0 to 1) but at the same time feel this is more intuitive since the first platform I target is 800x480 and I already kind of have a good udnerstanding of dimensions and such for that.
So my question is, is it really that bad to target a specific ccreen res then in the engine side modify this res to meet different platforms?
