Megaman | Unity project that recreates the Airman level | Game Engine library

I'm new to this topic of aggregations. I have in my database a structure like this:

I am going through the tutorial and doing everything as it says until I get to this section of the tutorial where it throws me this error. I have the hero class defined so I am confused as to why it is throwing me this error. I have restarted the program all together and even re-created the mock-heroes type script. I am using Visual studio code so here is my code for the two files:

Hero class defined in hero.ts:

I am new to github commands and I am a bit confused about what I am doing.

I want to delete the "MegaMan Game" commit, revert all changes, and make it dissapear from github history. Following this other stack overflow question Delete commits from a branch in Git, I ran the git reset --hard HEAD ~1 command. The commit seems to be deleted judging by the git log command, but on the github website it still shows that the "MegaMan Game" commit is still there. Also in source tree happens the same thing. The commit still shows there. I am a bit confused. Is the website wrong about the commits? Did I run the command wrong?

Here is an image with the exact commands and what git

This is a noob question. I need help to undestand how this works.

I'm attempting to recreate a certain fadeout effect the Playstation 1 game Megaman X6 does. The screen darkens with the darker colors becoming black first, and the lighter colors becoming black later on in the fade. It's like using bm_add but for making things darker instead of lighter. I've tried using bm_subtract, but it's the same as drawing a black rectangle that gradually increases its opacity over the entire screen. All the colors become fully black at the same. I have almost no prior experience with color blending and I still haven't wrapped my head around it yet, so I'm not sure what to do. All the blend modes I've tried don't work, and my internet searches have turned up nothing. I've become really frustrated, and I would appreciate it if someone could just tell me what I need to do.

My current code (sprDot is just a 1x1 image of a white pixel, and fadeAlpha stays between 0 and 1):

I currently have a sprite-based animation in which the player is running. I also have another animation where the player is running and holding a gun out and shooting, that plays at the exact same speed as the player running without the gun. The catch is, I'm using Animator.Play();

What I want is to start the player running with gun animation at the frame that the player running animation is currently at. For instance, if player running animation is at frame 20, and the player presses the shoot button, play the running with gun animation at frame 20.

Here is a rough example of my code so far:

Running this code errors when the page definitely exists as I use the python wikipedia library to get the page in the first place.

I am creating a game in pygame and I am trying to get the images to have their white backgrounds transparent, I did my research and tried set_colorkey and convert_alpha. Could someone tell me why this isn't working.
