UDK Units version 2

Max Height Jump = 52 udku
Max Double Height Jump = 89 udku
Max Distance Jump = 322 udku
Max Double Distance Jump = 499 udku

The actual udku conversions to real world measurements are not exact and do differ over different games.

Unreal Tournament games : 1 udku = 2 cm.
Gears of War : 2 udku = 1 inch.
Most licensees use a scale of 1 Unreal Unit to 1 cm.

The important thing is that unit conversions between development engines UDK 3DS and Maya are 1 for 1.

So for most cases : 1 udku = 1 3dsu = 1 mayau = 2 cm.

The overriding premise though is that what ever unit calculation you choose to use you must be consistent and all objects within the space must be relative to your chosen unit calculation.

I have some further reading links.

Java basic colors are heavy and few.

eg. setBackground(Color.orange);

But if you want your frames to match your OS colors you can access them;

eg. setBackground(SystemColor.inactiveCaption);

Or even better yet use a hex code;

eg. setBackground(Color.decode(“#FFFF00”));

Fibonacci - revisited

Wow, Grey Wolf continues to astound me.

He rewrote the Fibonacci JavaScript so that it builds an array and then returns the index value you wanted.
This allows for greater calculation values and no longer crashes your pc.
Negative values are a bit strange and huge numbers will more than likely return infinity.
var fibTicks = 0;

var FibonacciTerms = new Array();

function fibonacciR(term) {

// recursive fibonacci method (the higher the number the more times the method gets called until we get to 1)

// we could use an array and iterate the array to find the value this would then be known as an iterative method.

// values greater than 30 are likely to crash javascript, for large numbers it is advised to use a language such as python using the recursive method.

fibTicks++;

if (term<=1) return term;

else return fibonacciR(term-1)+fibonacciR(term-2);

}

function fibonacciI(n) {

// iterative method, here we are creating a loop which will determine what the next term is, append it to an array of terms until it reaches the dssired number

var neg = false;

if (n < 0) { n = n - n - n; neg = true; } // deal with negatives (we could just return an error here)

fibTicks = 0;

var i = 2; // we already have the 0th and first term so start counting from the 2nd term

FibonacciTerms = new Array(0,1); // clear the list of terms, add the 0th and 1st term

while (i <= n) { // loop through until we reach the desired term

fibTicks++;

FibonacciTerms.push(FibonacciTerms[i-1]+FibonacciTerms[i-2]); // add the term to the array

i++; // add 1 to our loop incrementor

} // end of loop

var r = FibonacciTerms[n]; // put the N’th term in to variable ‘r’

if (neg == false) return r; // exit the function giving back the number stored in ‘r’

else return r-r-r; // exit the function giving back the negative value for the number stored in ‘r’

}

yClass is a type of xClass.

A XClass has 3 int states, x,y & z.

An object of the xClass may be created by providing a value for all 3 of these states and also by providing only x & y.

The yClass has 2 int states, a & b.

An object of the yClass may be created by providing a value for a, or values for both a & b.

The zClass is a type of yClass and has 1 int state called c.

An object of the zClass may be created with or without supplying a value for c.

Delimiters, Splits, Tokens, and Meta- Characters

So we have this text file that is full of World information on 10 players.

Each Player has the following information;

World Name
Player Name
Player Health
Player Strength
Player Intelligence
Player Location - each Player has a starting location

each location has 2 coordinates

X co-ordinate
Y co-ordinate

Player Inventory - each Player has 10 Items in their Inventory

each Item has 5 bits of Information

Item Name
Item ID
Item Weight
Item Value
Item Level

Now this information is all held in this World text file, but how do we read it effectively, it just seems to be a random wall of text.

We use a Delimiter.

In this case the delimiter is set as ;

What that means is when we scan the text file each character preceded by ; will be recorded as a string.

Each of these strings is called a token.

Each token can be broken down further into smaller tokens using the split function.

In this case we have

First split :
Second split @
Third split *
Fourth split #
Fifth split ?

The issue we come across is that some characters already have assigned functions; these are called Meta- Characters, and using them as delimiters and splits will cause hang and crash issues.

Meta-Characters . ^ $ | * + ? ( ) [ { \

If you precede Meta-Characters with two forward slashes \\ it will turn them into a literal character.

eg. scan.useDelimiter(”\\? “) or String[] StringName = Token.split(”\\* “)

Blog Task - The Constructor

Wow this turned out to be a big class.

I viewed this Player Account and treated it in a way similar to World of Warcraft.

Each player has a Player Account that must be set up before you can create avatars to play.

Each Player Account has required parameters and also have data types that are themselves class objects.

The DOB class has 3 states, dd, mm, and yyyy.

The Avatar class has 4 states, name, race, sex and class.

Blog Task - Encapsulation and Visibility

Accessors and Mutators allow exterior objects read or modify access to an objects public states and behaviours.

In UML diagrams each Accessor and Mutator is preceeded by a plus sign, ( + ), which identifies that the object state or behaviour is public.

In UML diagrams a minus sign, ( - ), denotes a state or behaviour is private, and as such is not acceable by on outside object.

What is an Accessor?

An Accessor allows outside objects to read the state or behaviour of an object.
Accessors are also known as Getters.

What is a Mutator?

A Mutator allows outside objects to modify the state or behaviour of an object.
Accessors are also known as Setters.

If …Then … Else statements

The If Then statement tests whether an If condition is true or false - if it is true Then will execute

The If Then Else statements test whether an If condition is true or false – if it is true Then will execute – if it is false Else will execute

These can be used to test input values and match it against multiple conditions to provide an outcome based on whether the value is validated as true or false

The value will be tested against each condition, in order, until it is found true

If none are true Else will execute
