Simple game

Currently making a simple game where the player character (a ball) moves into a goal, and then the goal moves, but I can't even test if the rest of my code works properly as no matter what, the form won't detect key presses (yes i have keypreview true and keydown has been assigned something)

I used to be getting an exception, but once I sorted that out all of a sudden it stopped detecting any sort of input

What's your project environment?

selbbuBOP•6/9/25, 1:30 PM

I'm doing this on a .net form in vs

Ok so winforms

selbbuBOP•6/9/25, 1:30 PM

yeah

TheBoxyBear•6/9/25, 1:32 PM

You have the keydown event handler but is it actually bound to the event?

selbbuBOP•6/9/25, 1:33 PM

is that setting keydown to form1_keydown in properties?

TheBoxyBear•6/9/25, 1:33 PM

Also what keys are you using? Do regular letters fire the event?

SselbbuB is that setting keydown to form1_keydown in properties?

TheBoxyBear•6/9/25, 1:34 PM

yes

selbbuBOP•6/9/25, 1:34 PM

yes I've done that

selbbuBOP•6/9/25, 1:34 PM

that's what stopped the exception form happening

TheBoxyBear•6/9/25, 1:34 PM

If you're using special keys, you should handle the previewkeydown event instead

TTheBoxyBear Also what keys are you using? Do regular letters fire the event?

selbbuBOP•6/9/25, 1:34 PM

wsad and the arrow keys

TheBoxyBear•6/9/25, 1:34 PM

You can try swapping events but wasd should still be detected by keydown

selbbuBOP•6/9/25, 1:36 PM

that didn't work

TheBoxyBear•6/9/25, 1:38 PM

What element is in focus? The form or a control?

selbbuBOP•6/9/25, 1:39 PM

the form..?

selbbuBOP•6/9/25, 1:39 PM

i think..?

TheBoxyBear•6/9/25, 1:40 PM

You can try settng to the focus to it

selbbuBOP•6/9/25, 1:41 PM

how?

TheBoxyBear•6/9/25, 1:41 PM

Focus()

Focus()

selbbuBOP•6/9/25, 1:42 PM

where would I put that in the code? (sorry, this is my first time making a form do more than simple calculations)

TheBoxyBear•6/9/25, 1:42 PM

It's a method of the form

TheBoxyBear•6/9/25, 1:43 PM

It also depends how the rest of the project is

selbbuBOP•6/9/25, 1:43 PM

TheBoxyBear•6/9/25, 1:43 PM

So the link from earlier is your entire code?

selbbuBOP•6/9/25, 1:44 PM

yeah

TheBoxyBear•6/9/25, 1:45 PM

If there's nothing pulling focus, put the focus at the end of the constructor

TheBoxyBear•6/9/25, 1:46 PM

If that still doesn't work, sadly I can't help much further. I also checked a couple StackOverflow threads

selbbuBOP•6/9/25, 1:46 PM

like this..?

TheBoxyBear•6/9/25, 1:47 PM

Focus in the constructor to make sure the event is fired

TheBoxyBear•6/9/25, 1:47 PM

(The function named after the form)

selbbuBOP•6/9/25, 1:50 PM

wait I've just realised the code isn't even running at all, the labels don't even change

selbbuBOP•6/9/25, 1:51 PM

they stay as labe 1 and label 2

selbbuBOP•6/9/25, 1:51 PM

when I have it so they change to time and scoree when i load it

TheBoxyBear•6/9/25, 1:51 PM

Using a different form?

selbbuBOP•6/9/25, 1:52 PM

same thing, just when trying to run it, it's as if i haven't written any code

selbbuBOP•6/9/25, 1:52 PM

TheBoxyBear•6/9/25, 1:53 PM

Double check your files are tied to the right form

TheBoxyBear•6/9/25, 1:53 PM

The form to run is determined in Program.cs

selbbuBOP•6/9/25, 1:54 PM

TheBoxyBear•6/9/25, 2:03 PM

So it runs Form1

TheBoxyBear•6/9/25, 2:03 PM

Does it hit breakpoints in the constructor and other functions?

selbbuBOP•6/9/25, 2:03 PM

TheBoxyBear•6/9/25, 2:04 PM

and _Load

TheBoxyBear•6/9/25, 2:04 PM

Click in the margin to place a red dot on an instruction line. Execution will stop at the line if that code is reached

TheBoxyBear•6/9/25, 2:05 PM

(c++ because that's the project I have access to right now but it's the same in c#)

TheBoxyBear•6/9/25, 2:07 PM

Your program will freeze but that's expeted, just reclick the Run button in vs to resume
