Hi.
I want to create a mobile game using only GUI elements. I will use a ZOOM adjustment mode for all nodes, and I believe that adjustment is calculated like this:
local DISPLAY_SIZE = vmath.vector3(640, 1136, 0)
local window_size
do
local width, height = window.get_size() -- width = 720, height = 1545
window_size = vmath.vector3(width, height, 0)
end
local adjust_zoom_scale = math.max(
window_size.x / DISPLAY_SIZE.x,
window_size.y / DISPLAY_SIZE.y
)
Let’s say I want a GUI node that always spans the width of the window, I could do this:
It also depends on your camera projection type.
For default projection, you can get adjust_zoom_scale like this
local display_size = vmath.vector3(640, 1136, 0)
local width, height = window.get_size()
local window_size = vmath.vector3(width, height, 0)
local scale_x = window_size.x / display_size.x
local scale_y = window_size.y / display_size.y
local actual_display_height = scale_x > scale_y and display_size.y or window_size.y / scale_x
local adjust_zoom_scale = actual_display_height / display_size.y
I’m just wondering why you choose to use gui.ADJUST_ZOOM for all your nodes? When you change your node size, it means that you can not use size mode Auto, a useful mode for your node texture
Yes, sorry for confusing information, I meant there are 3 projection types in your camera library. In case of using it, no differences with gui for each type?
Hi.
I use gui.ADJUST_ZOOM for all nodes because when I switched from computer to mobile phone, everything was so small whereas with gui.ADJUST_ZOOM everything was suitable, whether on the computer or the mobile phone.
My application requires text input, scroll windows, lists, and I wonder if Defold is a good choice when I see Flutter offering animations and particle systems (https://codelabs.developers.google.com/codelabs/flutter-next-gen-uis). The test I did with Defold launches in 3 seconds on a mobile phone and Flutter in 5-6 seconds. I like the lightweight nature of Defold but Flutter seems interesting for my case.
I don’t have any experience with Flutter so I can’t say. But I know it is becoming more and more popular. You should evaluate it. Remember to also look at things such as cross platform support, launch speed (you already tested this), install size and so on.
If you do wish to continue with Defold then make sure to look into Druid, a nice UI library for Defold. It has all the features you need:
I guess you are trying a way to have a fullscreen covered node? If yes, you can do that as following
local display_size = { width = 360, height = 767 }
local window_width, window_height = window.get_size()
local sx = window_width / display_size.width
local sy = window_height / display_size.height
local scale = math.min(sx, sy)
local actual_width = window_width = scale == sx and display_size.width or window_width / scale
local actual_height = window_height = scale == sy and display_size.height or window_height / scale
local node = gui.get_node("node")
gui.set_position(node, vmath.vector3(display_size.width / 2, display_size.height / 2, 0)) -- set it centered of the screen
gui.set_size(node, vmath.vector3(actual_width, actual_height, 0))
If you want to have fullscreen covered but by scale
local bg_node = gui.get_node("bg_node")
local bg_size = gui.get_size(bg_node)
local bg_scale = actual_width / bg_size.x
if bg_size.y * bg_scale < actual_height then
bg_scale = actual_height / bg_size.y
end
gui.set_scale(bg_node, vmath.vector3(bg_scale))
Ok. I continued with my method since your code produces the same thing anyway. The application launches in fullscreen, and you can move the rectangle with the mouse or your finger.
EDIT: I deleted the zip file, it’s no longer needed.
