actor needs to stop another actor?

By Serhil, with no replies.

I have an actor named Brick and another actor named Angrybird. The actor Brick only stands in my world and the Angrybird can fly anywhere. I want that the Brick stops the Angrybird from moving when he hits it, so that when the Angrybird hits the Brick, he needs to stop and the Angrybird should go around the Brick to proceed its flight. anyone who knows how to do this? this is the movement code from my Angrybird: void move() { int speed = 10; if(Greenfoot.isKeyDown("up")) setLocation(getX(), getY() - speed); if(Greenfoot.isKeyDown("down")) setLocation(getX(), getY() + speed); if(Greenfoot.isKeyDown("left")) setLocation(getX() - speed, getY()); if(Greenfoot.isKeyDown("right")) setLocation(getX() + speed, getY()); }

unbounded world

Last reply by nccb, almost 13 years ago:

I'm afraid greenfoot has no conception of a viewport. There is the world, which is displayed from 0,0 to width, height. If you want to scroll around a large world, you would need to do so by moving all the actors in the world (which is only four lines of code: get a list from the world and call setLocation on them).

for loop

Last reply by IsVarious, almost 13 years ago:

Your question is a bit confusing, is it that you're wanting some code which checks to see if the snake is hitting a certain object, or are you asking how to create objects/images which you can use as a wall to block the snake?

I'm a bit confused about your questions. Is it that you're trying to make it so when the user clicks on the object, it is then pushed in a new direction? If this is the question, I would start with an if statement that checks to see if that object is clicked on, and then have a method that does what it is you're wanting done. For example, if you're wanting to push the ball in a new direction. You would write like this... <Code Omitted> Then you would write the method that does the action you're wanting

Save files

Last reply by nccb, almost 13 years ago:

When running in the IDE, it stores the data locally in a file (and handles all the file-writing and file-reading for you). When you export your scenario to the greenfoot.org website, the data is stored (per-user) on our server, but you don't have to modify your code at all -- you use the same code locally and exported, and Greenfoot does the right thing in each circumstance.

What does the delay() method do?

By RedPhoneBooth, with 3 replies.
Last reply by danpost, almost 13 years ago:

In this case, you need to add an object boolean variable, let us call it 'swooshing' in the actor's class: <Code Omitted>Then, in the act() method you will need a few checks 1) if swooshing and either the spacebar is down or the swoosh object is still there: do not do anything 2) if swooshing and the spacebar is not down and the swoosh object is gone: reset swoosh 3) if not swooshing and spacebar is down: begin swooshing

You must do more than create an object to get its location. Creating an object does not automatically put that object in the world. You need to find a method to add that object into the world before you can get its location in the world. Let me ask you this (maybe you might get some ideas on how to program this): when the ball and the player 'see' each other, which should control which? I mean, in football, does the football control the player or does the player control the football? Think about what this might imply.

Thanks for the answers.i know player should
