Everytime i tried to fill in your code the jumping and moving stopped working

The tutorial describes an Actor following type, which can be easily modified to scroll only horizontally. To assist with your codes, you will need to show what you did. You should have an unmodified Scroller class added to your project, a reference to a Scroller object in your scrolling World subclass (with a Scroller object assigned to it);, and an act method in that world that controls what the Scroller object does. Show world class co

How do I make more accurate hitboxes?

Replied to by danpost, 6 days ago:

Hello. I am currently about to start work on a project for school, a shooter-platformer game. Is there any simple way to make more accurate hitboxes? (atm I am just using isTouching(_cls_) and removeTouching(_cls) and the hitboxes are all square and too big)

More information is required. The "too big" part may be due to excess transparencies along the outer edges of some image(s). The required hitbox needs to be described as to what is and is not allowed as far as collisions go.

How can I make my code only spawn one new object upon key press?

Another issue is that you most likely shouldn’t create a GreenNote object from inside the GreenNote class. The world should spawn the objects. Otherwise, each GreenNote object creates another object which can escalate quickly.

I have a little space game with a rocket that tries not to touch asteroids. now, that worked well, the rocket touches the asteroid, the game restarts. The problem is, I made another object, a little red dot and I want, when Rocket touches it, to give it something (movement speed +1, for example). I tried everything, nothing works, didn't found something on internet neither. It's my first day, what to do? Also, the ball does not disappear when I touch it

hello, when I save the world, I keep all the classes in a specific position and when I save it, All the classes are not in the place where I kept them. what could be the problem ?

I believe the class tree is built, or rebuilt, during compilation based on how the dependencies are found in the code during compilation. I doubt it would be very easy to control the order of class positions precisely.
