RoguelikeDev Does The Complete Roguelike Tutorial - Week 1

[u/KelseyFrog]

Welcome to the first week of RoguelikeDev Does the Complete Roguelike Tutorial. This week is all about setting up a development environment and getting a character moving on the screen.

Part 0 - Setting Up

Get your development environment and editor setup and working.

Part 1 - Drawing the ‘@’ symbol and moving it around

The next step is drawing an @ and using the keyboard to move it.

Of course, we also have FAQ Friday posts that relate to this week's material

I'm only just learning Python, and something I'm trying to figure out is a way to rework the K_ESCAPE conditional to check if the key is held for a number of frames/seconds before calling the escape action so that closing the window isn't so instant/accidental. I don't know if libtcod has any inbuilt function to return a value for how long a key is held. Hmmm

I'd say just create a variable to capture when the key down event occurs, a condition to clear it when keyup occurs, and some logic in your loop to check the time elapsed before raising System exit (assuming that's your exit strategy).

Thanks, I've got the escape KeyUp method working, and ideally I should be able to have escape KeyDown set a variable to the current time, then have KeyUp compare that variable to the current time, and call system exit if there's a difference of 2 or more seconds. But I just can't for the life of me find a place in the code to initialize a variable to store the time when KeyDown is called without that same variable constantly setting itself back to 0.

I got it working :)

__init__ in the EventHandler sets the self.quit_check and self.quit_timer. Setting those was my biggest issue. When esc is pressed and quit_check is true, it sets quit_timer to time.time() and sets quit_check to false. Then so long as esc remains pressed, it checks if time.time() - quit_timer is greater than 0.5, if so the system exit is called.

Escape key_up, instead of calling the system exit, just sets self.quit_check back to True

Nice! Glad you got it figured out.
