drawline

I'll write better next time, for drawLine, use setColor, otherwise it's white, I do not understand, I thought I would see a black line without setColor must always use color, what

Any GreenfootImage object you create by giving dimensions of the image will draw BLACK without having to specify. The setting of the color WHITE for the background of the world is done by greenfoot. I have had no reason to test other images (those created by other constructors), so I cannot say anything about them at the moment (would be easy to check, however).

this line of code is good or not, it does not work yet i followed the API

You only have 4 points listed in the arrays -- not 5. Also, both arrays are new.

the last time you gave me the code that moves the object with the cursor, my question is how to connect for example, your code with the cursor with drawLine or other, with that I can draw lines with the cursor, I do not know not if you understand me. for example, there are a lot of code methods, I am trying to understand how to connect two code methods or should I rewrite the code method with two code methods it's hard to connect once you have all the formulas, I'm not trying to create anything but just understanding I do not know if I made myself clear Thank you for your help

I would make use of the position/movement of the object following the cursor. Before it moves AND after you know how it is going to move, you could use something like this (dx and dy are the distances to be moved horizontally and vertically);

how to link this code above with this code below, i try to understand how to do Thank you for your help

thank you, I'll never think something like this, finally, i have a lot to learn i added setColor in myWorld and it works on the other hand, I added also public void drawLine in Actor, I do not know if it's worth adding it, it works without also with public void act
