it worked but if I play my game and die, I get an error.

What (exactly) was the error? What is the coding around which the error occurred.

I seared on the internet for solutions and found this code , which worked for me even if I died: << Code Omitted >> unfortunately I don't understand what the code does xD. Could someone explain this please because I need to explain my code in school.

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.

hitboxes are very inaccurate to the real hitbox of the bullet

By cq1um, with 2 replies.
Last reply by danpost, almost 5 years ago:

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 code (Bullet and Car classes).

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,
