While loop not possible for processing input

sstelkar

I'm developing a word search game and currently stuck at input. In Godot while loop not possible for input function and input in process function. So it is not possible to drag a line like in word search program and clear the points if word doesn't match So while mouse pressed function not possible. Since we are using if for input function it will always be one point at a time and adding points will not be smooth

You don't need a while-loop to handle dragging. Here's one way to do it, although it's dragging a sprite rather than a line. https://www.davidepesce.com/2019/10/14/godot-tutorial-5-1-dragging-player-with-mouse/

Here I'm talking about adding points to the line. The link you quoted is one for sprite. How are both even comparable. If you had used a word search game you would understand, what I mean.

The problem is the logic of your code, not Godot. The input won't change until the input function is finished; if the while loop is checking if the input has changed in the while loop, then the loop will run forever.

don't you think it makes sense to have "while loop" for mouse button pressed. anyway i did a work around for my problem

So, while the button is pressed you want the rest of the program to stop?

okay tell me how do you get the start and end point of a single drag

i want the start and end position of a single drag

You would use the _input function for this. A while loop won't work (and will likely just freeze your program). You can look at the mouse motion, and update the line when the mouse moves.

I'm not sure what you are doing, but coroutines are used for waiting for an event to finish. You might want to check them out in the docs. However, you can't put them in a process function, which is probably your problem with using them in a while loop.
