StackTrace when no sound available

By Forj4K, with 1 reply.
Replied to by danpost, almost 8 years ago:

You can comment out all lines in the Explosion class that deal with the sound. That way you are not deleting them and the sound files (whether you delete the lines or not) remain in the 'sounds' folder of the scenario directory.

There is only one instance of object of om and xm

Then just use: <Code Omitted>and similar for the 'xm' class. To note, I do not see how you would get the IndexOutOfBoundsException with what you had above.

Why is it a poor way? Checking the number in an array based on your location is faster than checking for intersection with a wall object in the world.

Even better might be to add invisible intersection actors at any place pacman can turn. They could even hold which directions are available to go from their individual locations. In other words, instead of detecting walls, detect the intersections, which gives where a turn can be made (by its location) and which ways are available to go from there (by fields).

greenfoot.core package api?

By CubeGamer6, with 1 reply.
Replied to by davmac, almost 8 years ago:

The greenfoot.core package is not meant to be part of the public Greenfoot API, that is, you aren't really supposed to use it from scenarios. If you do, your scenario won't work as a HTML5 app if you export it here, and might not work between different versions of Greenfoot (because the greenfoot.core API can change incompatibly between versions). If you really want to know what classes and methods are available in the current version of Greenfoot, you could check the Greenfoot source code (which you can get from the Download page).

Midterm project - wanting to make a rhythm game of sorts

Last reply by Vercility, almost 8 years ago:

@Vercility: Change which direction they're coming from. Say the O is the actor, and the () is the arrow; O <() Halfway through, it would go to O ^ () switching from coming from the right to coming from the bottom. I'll try to code what you all said in class today and update as I have problems. Thank you for the help!

Thats fairly easy. Assuming your actor is right in the middle. Say your arrow comes from the left, if you wanna swap the direction you just need to remember how many pixels the arrow has already traveled from left to right (x axis)
