Help with optimizing my EnemySpawner and Animation Class

You should be able to see immediately from the use of your 'for' loops that your way would be more cpu intensive. These method calls, on the other hand, are quick and simple (just returning values that are already saved in fields -- no counting required).

should I use if or while

Last reply by danpost, over 11 years ago:

If you have more than one 'for' loop in the program, you should be able to convert one of them to a 'while' loop easily enough. For example: <Code Omitted>can be converted to this <Code Omitted>The 'do-while' loop is a bit different than the 'while' and 'for' loops in that the condition to continue the loop is checked at the end of the block instead of at the beginning. So one iteration of the block must be allowed to execute. It would be alright to convert the above into a 'do-whil

Unable to Install Kinect OpenNI driver for Windows

By Champ, with no replies.

I'm trying to connect Kinect with Greenfoot. I'm following the instrcution as mentioned on below URL: http://www.greenfoot.org/doc/kinect/windows.html Here it is mentioned that to install driver I need to run this command: bcdedit /set testsigning on However when I ran this command by following the instruction then it I'm getting an error as mentioned below: C:\WINDOWS\system32>bcdedit /set testsigning on An error has occurred setting the element data. The value is protected by Secure Boot policy and cannot be modified or deleted. I stopped here as I believe it is must to run the above command successfully then only I should install the driver.

You now have in the Zombie class the same issue you had in the Bullet class. One method removes the actor and the following code is executed without regard to whether the actor is still in the world or not.

Increasing speed per click?

By lamboa, with 3 replies.
Last reply by wabuilderman, over 11 years ago:

you would have a variable, "speed", and you would increase it by a certain amount whenever the mouse is clicked. If you don't know how to code that, try looking at the API. Here. It would look something like this: <Code Omitted>

Continuously moving object?

By miegoer, with 1 reply.
Replied to by wabuilderman, over 11 years ago:

What you need to do is have a "speed" variable. increase the variable when you want it to move. In the act statement, simply call a move(speed) function. This way, if speed = 0, you don't move, if it is greater than 0, it will move forward.

Get more than ONE object at OFFSET?? (:

By JohnVarick, with 1 reply.
Replied to by danpost, over 11 years ago:

Vague. Is the "another object" also a Star object or of a different type? (from the title, I would presume the "another object" be of the same type). If the same type, then use 'getObjectsAtOffset'. If not, use something similar to how the Border was removed when the Heart2 was eaten (from your previous discussion thread).

Intersection help! :)

Last reply by danpost, over 11 years ago:

You could make use of the 'getObjects' method of the world class: getObjects(Border.class) or from the Actor class: getWorld().getObjects(Border.class) which creates a list of all Border objects in your world. The list will contain either one element (the one Border object in your world) or it will be empty (after the one Border object has been removed). The 'removeObjects' method of the world class can then be used, instead of the 'removeObject' method, to have any objects listed removed from the world:
