- Homework Statement
- Hello guys, if you don't mind, I will attach the whole exercise in the pdf(it is the 1st difficult task RPG_game).
This is the description of the exact task(task 3 of difficult task 1) WITH CODE HIGHLIGHTED(function starts from line 36, the other stuff is for context):
[3 Points] Write a function player_move that takes the same three parameters as the previous function, plus a fourth parameter direction, which represents the direction of the move (“UP”, “DOWN”, “LEFT”, “RIGHT”). The function determines whether the intended move of the player is possible, and what consequences it has for the player’s health. If the move is possible, the function returns a list that includes (1) the player’s health after the move, (2) the player’s position, and (3) the updated state of the world. If the move is impossible, the player does not move and nothing changes. Should the player die, they are no longer present in the matrix, since the position where they died will be occupied by the enemy that defeated them. In that case the returned position is the position where the player died.
- Relevant Equations
- So It seems to me that i have done everything correctly, comparing it with the test underneath the file as well, yet it doesn't seem to work out.
Can someone help/steer me in the right direction please?
And perhaps, if possible, give some advice on how I have written the code. It's the first time I use 2D Lists in matrix-form, just something to keep in mind :'D
I have also put some notes on what is to be done in the problematic function
Note also that this is not homework, but am just preparing for an exam.
Thanks in advance!
forgot to provide the code here, so here it is:
