@PaulVictorey 6 ай бұрын

@5:08 You could have also used the walrus operator to both assign to the variable and use the variable as a parameter to add_child. You could even have compressed your entire spawner script to a single line by using a tuple along with the walrus operator, for example add_child((enemy := load(...), enemy.set_position(...))[0]). Tuples are probably your best method to merge multiple expressions into a single line of code without using semicolons.

If you use godot and using godot doesn't count as using lines, modifying it wouldn't count as using lines too. So you could work out makros into the engine - this way you could define a makro for "extends Node2D; _physics_process(delta):" and can save a line with MAKRO [stuff that is made] in the enemy/player node. (afaik godot doesn't have makros because they are stupid)

At my school one of the projects we had to do was to make a game of tic-tac-toe in python, however this was boring as I already knew how to code. A kid named Joshua and I got into a competition to complete the project in the fewest line of code. In the end we had user input and the code printed error statements and continued running properly with false inputs. the code also refreshed infinity meaning you could win one game then instantly roll into the next game. We managed to get it down to 2 lines in total. The first line defined the board and the second line was a very long in line while statement that contained all the code for actually running the game.
