So I just discovered something pretty horrific today... after 6 months of work.... I have moved from a smaller monitor to a larger one. So my resolution settings have changed. When I opened my project some of my sprites are all over the place on the screen. Even though they are set via percentages nothing is lined up properly anymore.

Am I to assume that from the user perspective.. those that play the games we make will each experience different results with our UI?

I'm assuming this means I will have to create another script that detects the screen resolution (if it exists) and modify everything position around that.

Hi teabone, yeah I had this as well, you need to place this before any ShowSprite() or PasteSprite() commands

SetSpriteSize ( mySprite , sizeX , sizeZ ) -- passing -1 as one of the params ensure the sprite retains its aspect ratio

obviously using your own variable names, my note scripts were hit bad, but I found 45, -1 work to display my notes on the right of screen in any resolution, the -1 keeps the sprites aspect correct. Hope that helps

Having a bit of a mind-blank morning. Where would put the -1 ?

+ Code Snippet

function showimage_init(e)

spr_created=0

end
 
function showimage_main(e)

if spr_created == 0 then
spr0 = CreateSprite(LoadImage("scriptbank\\images\\001.png"))

SetSpritePosition(spr0,200,200)

spr_created = 1

end

PasteSpritePosition(spr0,0,0)

end

EDIT: I think maybe the mistake I made was trying to trick the system into forcing the image exactly where I wanted by making the PNG the size of the entire screen with mostly negative space and having the actual image located somewhere within.

Also noticed my text elements are no longer aligned properly. :/

Hi all,
Yeah had this issue myself. An never figured out the fix....

@Tarkus1971: So should Teabone's code be something like this:

+ Code Snippet

function showimage2_init(e)
 
spr_created=0
 
end
  
function showimage_main(e)
 
if spr_created == 0 then
spr0 = CreateSprite(LoadImage("scriptbank\\images\\001.png"))
 
SetSpritePosition(spr0,200,200)
SetSpriteSize(spr0,50,50-1)
 
spr_created = 1
 
end
 
PasteSpritePosition(spr0,0,0)
 
end

Would be nice to have a sprite layer like Construct2 - you place whatever you want on it at design time, and it gets scaled to whatever resolution the monitor is at automatically

This is part of my note script. 45,-1 means 45% of screen and -1 keeps the aspect ration correct

+ Code Snippet

if g_KeyPressE == 1 and firstpress == 0 and keydown == 0 then
				note = LoadImage("scriptbank\\images\\_OutpostInsideV3\\003.png")
				note_sprite = CreateSprite(note)
				SetSpriteSize ( note_sprite , 45 ,-1 )
				SetSpritePosition(note_sprite,53,5)
				PlaySound(e,0)
-- Place spawns here 

				Hide(e)
				keydown = 1
				firstpress = 1
			end

For this just add -1 to the Y co-ordinate. That way you will get the percentage size across the X axis as you want and GG will automatically keep the Y axis a the proper size accordingly. It's always best to get a handle on this at the start of your project, especially if you are using a lot of sprites

As far as I know this should work on any resolution as it was coded to take different resolutions from the start. With something like this it can be quite complicated and different resolutions can affect all sorts (not just the sprites look).

Okay I'm going to have to try this today. I have made an inventory system where you move around icons... so everything has to line up preciously.
