First, the actor is coded to move at a speed of three,
Alright: <Code Omitted>
I'm not quite sure how this code works (if (Greenfoot.getRandomNumber(100) < 10)) but I believe it's stating that between moving 10 and 100 units on the map, which then the actor will turn 45 degrees
I believe you mean: <Code Omitted>
Need help with delay

I have like 40 pictures showing one by one with a delay of 0,5 sec , so that’s 2 FPS which is a low framerate , this should not be the issue here
You should probably run your scenario at normal speed (60fps ~ 50speed) and just change the image every 30 frames. For most scenarios, using frames makes for more consistent behavior. Any lag could throw timing of interplay of actors off when using system time.

the image of the bullet is transparent, yes i have tested the hitboxes https://www.greenfoot.org/scenarios/9908 < here, and the hitbox seems fine to me on the car (that is being shot at) aswell as the bullet.
Do not link someone else's scenario for a problem in one of yours. Provide
your

New to Greenfoot... How to make object not protrude world edge.

I would like to make my actor not protrude world edge. It kinda goes halfway and then it blocks the move input.
The actor's image is centered at its location. Use actor's location and the width of its image to adjust location of actor when too close to an edge (after a move).
OK. I somehow figured it out! Thanks, your reply helped me get to the bottom of it ;)

How do I save a Greenfoot projekt as a Greenfoot file(so you can open it directly not as a Folder)?
Just share it as an application. It will be saved as an
Executable Jar File
(where
"Open
" runs the program outside the greenfoot application).

If the actor where the boolean IsDeleted is named Cut , so the reference to the boolean whould be : Cut IsDeleted ? ( ex : if ( Cut IsDeleted == true ) { ....} ) ?
Well, if
Cut
is the name of the class that creates the actor with the
boolean
, then
Cut
is not necessarily, and probably should not be the name of the reference (to avoid confusion). Example: <Code Omitted>With this line,
cutActor
is the name of the reference to the actor. <Code Omitted>Here,

I rebuit the code for this actor , but after i keep pressing the C button on my keyboard and i lift it at a random moment , i get an weird error << Code Omitted >> I think this error has to deal something with the fact that the compiler cannot find the Actor, but the actor is there
It is not the actor, but the world that it cannot find. Once the actor is removed from the world (line 31), the
getWorld
method will return a
null
value. Change lines 31 and 40 to: <Code Omitted>to abort the method when the actor
