Import the Animal class via the menubar 'Edit>Import class...' and look at the 'atWorldEdge' method and the 'eat' method. They should lead you to what you are looking for (you can use the 'this' keyword to refer to the object to be removed).

Spawning Objects At Different Rates?

By allyand17, with 2 replies.
Last reply by danpost, over 11 years ago:
I am not sure that I understand the 'good'/'bad'/'ok' fields. You should probably be using 'new good()'/'new ok()'/ new bad()' instead (using the proper class names, of course).

Boolean Statement

By SullyFish, with 4 replies.
Last reply by danpost, over 11 years ago:
Line 13 uses 'isTouched' as a condition (as if it was a boolean field). You must follow it with an empty set of parenthesis to call the 'isTouched' method which returns a boolean value (or just change it to 'touched' to get the boolean value directly).

Bullets go right through enemies some of the time and other times they kill the enemies. Help!

The 'update' method of the Infantry class does not look right. You set speed and health to zero by subtracting those values from themselves, then the object gets removed (because health is zero) -- the 'else' part will never execute. When is this method called and from where?
all my unit types (Infantry, Medium, Speedy, Ultra, Heavy) all inherit from an empty class called Enemy so I can easily check if an actor is an enemy
Why is the Enemy class empty? You should put the common fields and methods in it INSTEAD of in each of the subclasses. If the subclasses have differen

If you have a Mac, Linux, or cygwin (on pc), you can use a handy little utility called curl, this will fetch documents from web servers and dump the reply back to the console. I use this utility within shell scripts to automatically check customer sites to make sure they are still up every 10 or 15 minutes. A utility like this can be used to increase the page views.

How to make an actor move slower than 1pixel per act?

i get an error saying "possible loss of precision, required; found: double"
I don't think that's the full error message! "required: int, found: double" You are declaring the variable to be an int - i.e. an integer, a whole number - and then you are trying to assign a decimal fraction to it. Declare the variable as a double! <Code Omitted>

Placing Objects

Last reply by danpost, over 11 years ago:
You will have three sets of information: (1) the top-left location coordinates for where counter zero will go (counting in java starts at zero) (2) the number of rows across and columns down that make up the total area where the counters are placed (3) the horizontal gap between each counter location across and vertical gap between each counter down Giving these data fields names: (1) topLeftX and topLeftY (2) rows and cols (3) hGap and vGap. Since, rows times columns is the total number of possible counters, each location can be arrived at by

How do you spawn the ground/player?

By PalmTree, with 1 reply.
Replied to by danpost, over 11 years ago:
Create them manually (using right clicking to create a 'new class' {instance}). Then from the menubar, select "Controls>Save the World". Open the world class code editor and see how the code was changed to reflect what changes you made after resetting your scenario. Follow through the new code to learn what it does and how to do it yourself.
