I have a question, its more an OS-based one.
I'm playing a video game and I want to be able to put a textual timer ontop of the game's screen as if it was a part of the game itself.
Now, I can write a program in any language that displays a TextBox with a timer on the screen, but if I run it, the game's process (lets call it game.exe) "loses" its focus and I get my TextBox focused and interactive by the OS.
Is there any option to display that text "ontop" of the game.exe that comes from an entire different process? as if there were "layers" to the screen. Also, this text shouldn't be intractable, clickable or make the game.exe process lose its focus.
Here's a very simple example I drew:
Thanks a lot!
Solved this using a window trick with python and tkinter with some windows api stuff.
The trick is to create a transparent non-clickable window and keep it always on top.
I've basically combined this answer with a bunch of simpler stuff like removing window's border and set to auto fullscreen.

Ok, so I've been tasked with creating a VERY simple GUI at work (I'm an intern). The task is to eventually connect to a machine and process real data, but right now I'm working on randomly generated sine data with noise. I've chose to work in Python 3.0, and use wxpython to create my GUI components.
As I want everything to appear on the same window, I'm using panels (hence wx.lib.plot.PlotCanvas rather than something like matplotlib.pyplot)
The problem that I have is that over time, the plot seems to 'expand' off of the panel. This is temporarily solved when I manually resize the window, but resumes again immediately after (you need to run the code to see what I mean).
Expansion over time in panel
Another problem (that has bugged me since I have started writing the code) is that sometimes when I resize the window (manually) or minimize it and then maximize it again, the timer randomly starts and stops.
I have tried all sorts of things (changing padding in sizers, extra arguments, changing time between refreshes GetBestSize()) but I believe that I simply don't understand wxpython well enough to identify where the problem is
I would really appreciate any help you can shed on either of these problems (I don't know, they might even be linked to each other).
FYI: I am not an experienced coder, and my code is not finished (I have more functions to code, but I feel like I should resolve this first). I have constructed this code by looking at different techniques from various tutorials and websites like stackoverflow, so I know it's not formatted well and could definitely be made more efficient. Also, I have removed some parts just to be safe about confidentiality - nothing important, just strings in messages.
PS: If you do have an easier way to do the whole plot/update thing that doesn't have this problem (preferably still in wx) I would be thrilled to hear that as well
And here's my code:
EDIT: Solved the expanding problem by using self.p2.SetSize((W+0,L+0)) instead of (self.p2.GetBestSize())
EDIT: Made transitions much smoother by just regenerating data and redrawing it on existing canvas in the evt_timer function (instead of recreating the whole canvas, which gave a blink-y appearance if you know what I mean)

I am very new to coding and I'm still trying different languages out, I started off with GameMaker Studio and changed to Godot due to its compatibility with Mac I might as well learn something newer since GameMaker has been out for quite some time.
I want to create a RPG game and apply animation to each direction the character moves but the animation only plays after the key is pressed AND lifted. This means that while my key is pressed, the animation stops, and the animation only plays while my character is standing still, which is the complete opposite of what I want. The script looked really straight forward, but doesn't seem to be working.
I would tag this as the GDScript language instead of Python, but I guess I'm not reputable enough to make a new tag, so I tagged it under python because it is the most similar.
#variables
extends KinematicBody2D
const spd = 100
var direction = Vector2()
var anim_player = null
func _ready():
set_fixed_process(true)
anim_player = get_node("move/ani_move")
#movement and sprite change
func _fixed_process(delta):
if (Input.is_action_pressed("ui_left")) :
direction.x = -spd
anim_player.play("ani_player_left")
elif (Input.is_action_pressed("ui_right")):
direction.x = spd
anim_player.play("ani_player_right")
else:
direction.x = 0
if (Input.is_action_pressed("ui_up")) :
direction.y = -spd
anim_player.play("ani_player_up")
elif (Input.is_action_pressed("ui_down")):
direction.y = (spd)
anim_player.play("ani_player_down")
else:
direction.y = 0
if (Input.is_action_pressed("ui_right")) and (Input.is_action_pressed("ui_left")):
direction.x = 0
if (Input.is_action_pressed("ui_up")) and (Input.is_action_pressed("ui_down")) :
direction.y = 0
# move
var motion = direction * delta
move(motion)
As you check the input in _fixed_process, you call anim_player.play() several times a frame, which always seems to restart the animation, and thus, keeps the very first frame of the animation visible all the time.
As soon as you release the key, anim_player.play() stops resetting the animation back to start, and it can actually proceed to play the following frames.
A simple straight-forward solution would be to remember the last animation you played, and only call play() as soon as it changes.
You need to know if the animation has changed
First you need to put these variables in your code:
var currentAnim = ""
var newAnim = ""
And then you add this in your _fixed process:
if newAnim != anim:
anim = newAnim
anim_player.play(newAnim)
To change the animation you use:
newAnim = "new animation here"
I have created a Gui in matlab which has three axes and i would like to change the scale to log and linear by right click on the particular figure and select the scale options(1.logarithmic 2.linear). I tried using the UIcontextmenu. But i didn't get the result.
firstcycle_mass = handles.Data1{1,1}(1:6392,1);
firstcycle_ioncurrent = handles.Data1{1,2}(1:6392,1);

X1 = str2double(replace_with_dot_firstcycle_mass);
replace_with_dot_firstcycle_ioncurrent = strrep(firstcycle_ioncurrent, ',','.');
Y1 = str2double(replace_with_dot_firstcycle_ioncurrent);
axes(handles.axes1);
plotline= plot(X1,Y1,'r');
xlabel('Mass [amu]');
ylabel('Ion current [A]');
c=uicontextmenu;
plotline.UIContextMenu = c;

m1 = uimenu(c,'Label','logarithmic','Callback',#setlinestyle);
m2 = uimenu(c,'Label','linear','Callback',#setlinestyle);

I am trying to get my buttons to stay "pressed" once it is released. Right now I am using the improved Buttons Module for corona and I have the default image being the button looking unpressed, and the over image being replaced by an image that looks pressed.
What I am trying to do is once the button is pressed, it stays on the over image. Here is how my code is set up for the button I am testing it on.
local digButton = buttons.newButton{
default = "digButton.png",
over = "digButtonPressed.png",
onEvent = digButtonFunction,
id = "dig"
}
digButton:setReferencePoint(display.CenterReferencePoint)
digButton.x = display.contentWidth/5
digButton.y = display.contentHeight/1.9
Also, I have a function (digButtonFunction) that sets the id of this button to a variable to be used to run an if statement for when the user pushes a button following this one.
This sounds to me like what you really want is a switch. Buttons are not really designed from a UI perspective to do that. The down-state is there just to give feedback to the user that some action happened.
If it were me, I'd not use the button bit at all, but load in to images using display.newImageRect() and draw the downstate first, then the upstate. Built a touch event listener on each one that will hide one or the other. I do this in my games for my sound on/off buttons.
local soundOn = true
local soundOnBtn, soundOffBtn
local function soundToggle(event)
if soundOn then
soundOn = false
soundOnBtn.isVisible = false
soundOffBtn.isVisible = true
else
soundOn = true
soundOnBtn.isVisible = true
soundOffBtn.isVisible = false
end
return true
end
soundOnBtn = display.newImageRect("images/switch_on.png", 46, 36)
soundOnBtn.x = display.contentWidth / 2 + 25
soundOnBtn.y = display.contentHeight / 2 - 15
