imageplayer | jQuery plug-in : image player

I have an error from ESlint, but I don´t understand why. I have read these:

• Expected 'this' to be used by class method
• Eslint : Expected 'this' to be used by class method
• How can I fix 'warning Expected 'this' to be used by class method ' eslint error?

and this:

• https://eslint.org/docs/rules/class-methods-use-this

I still don't understanding what am I doing wrong.

My class

I made this code and when I run the program, I only get a black screen. There's no error about not being able to load images.

The code essentially goes like this: 1. Draw the map and the player (this part worked at some point but I don't have the last version of the code anymore) 2. Get the position of the player (this works)

These are the parts that don't work: 3. Update position of the player 4. Draw map & draw player again

I'm trying to show some photos on a website. Everytime I try, I get this error:

Cannot read property 'length' of null

I have a react component that uses Axios to get a bunch of photos from an API.

It works, but now I don't know how to display the images in the component.

How can I use the array of photos and display them in my component?

Here is a screenshot of the array returned by axios:

Here is my component:
