The GameDev.net FreeBook is relevant to game designers, developers, and those interested in learning more about the challenges in game development. We know game development can be a tough discipline and business, so we picked several chapters from CRC Press titles that we thought would be of interest to you, the GameDev.net audience, in your journey to design, develop, and market your next game. The free ebook is available through CRC Press by clicking here. The Curated Books The Art of Game Design: A Book of Lenses, Second Edition, by Jesse Schell Presents 100+ sets of questions, or different lenses, for viewing a game’s design, encompassing diverse fields such as psychology, architecture, music, film, software engineering, theme park design, mathematics, anthropology, and more. Written by one of the world's top game designers, this book describes the deepest and most fundamental principles of game design, demonstrating how tactics used in board, card, and athletic games also work in video games. It provides practical instruction on creating world-class games that will be played again and again. View it here. A Practical Guide to Indie Game Marketing, by Joel Dreskin Marketing is an essential but too frequently overlooked or minimized component of the release plan for indie games. A Practical Guide to Indie Game Marketing provides you with the tools needed to build visibility and sell your indie games. With special focus on those developers with small budgets and limited staff and resources, this book is packed with tangible recommendations and techniques that you can put to use immediately. As a seasoned professional of the indie game arena, author Joel Dreskin gives you insight into practical, real-world experiences of marketing numerous successful games and also provides stories of the failures. View it here. An Architectural Approach to Level Design This is one of the first books to integrate architectural and spatial design theory with the field of level design. The book presents architectural techniques and theories for level designers to use in their own work. It connects architecture and level design in different ways that address the practical elements of how designers construct space and the experiential elements of how and why humans interact with this space. Throughout the text, readers learn skills for spatial layout, evoking emotion through gamespaces, and creating better levels through architectural theory. View it here.

Need MAJOR help please!

2 posts in this topic

I am a 2nd year programmer in a computer tech class in school. I need help in a couple of areas, and any help is appreciated!


mcGrass1.addEventListener(

How would I make it so that when one of my objects touch another, it moves to another frame? Need help finishing the above code.



if (mcMonster.hitTestObject(mcLine14)){
mcMonster.y -=20
}

Pretty much the same thing as above, but that it bounces off the "Line". The code above does not work.


function numberOne(low:Number=1, high:Number=99):Number
{
return Math.floor(Math.random() * (1+high-low)) + low;
}

Here, I am trying to generate a random number. But, I cant get it into a string so I can export it to a text box on another frame. Any ideas?

And lastly:


if numberOne + numberTwo == 100 >={
numberOne = 34 && numberTwo = 13

I am checking my two random numbers so as they dont equal over 100. It dosen't work. Any ideas?

>>How would I make it so that when one of my objects touch another, it moves to another frame?

The problem you are talking about in the first two items is called "Collision Response". Google for it. It can be tricky to solve, especially when objects are being pushed against other objects or into corners. Imagine fifty creatures in a long corridor, and you attempt to push them in deeper even though they are fully compressed into the corridor already. Good code can handle that.

>> I am trying to generate a random number. But, I cant get it into a string so I can export it to a text box on another frame. Any ideas?

Your solution for the first part is very close. Why are you generating a floating point number and then casting to an int? Just use an int directly:

[CODE]
Random rand;
return rand.nextInt(max - min + 1) + min
[/CODE]

As for getting it to a string, Java's string classes provide many ways to do it. I'm sure you can find one or two through your IDE's autocomplete, or the web, or a book on the subject.


>>I am checking my two random numbers so as they dont equal over 100. It dosen't work. Any ideas?

I'm still trying to figure out how you even think that code does something useful. Do you understand what those operators actually do? Why would you think it does what you described?

Explain the logic to someone of what you are trying to do, make sure that logic is valid, then encode that specific logic.

It is called "collision response", and it can be very tricky. Imagine a long narrow corridor with 50 items in it fully compressed already. Then you try to push another one in. Google can help you find various ways to try to solve it.

Why would it?

Bouncing is usually reflection over the normal. It can be simplified in 2D, depending on the rules for your lines. Search button results in [url="http://www.gamedev.net/topic/510581-2d-reflection/"]this with formulas[/url], among other good results.

What part are you having problems with? Generating it? Turning it to a string? Exporting it?

Explain the logic you think would do it to someone else, make sure it is valid logic, then implement it.

Thanks for the fast reply.

Sorrry for not being clear. I need to get it in my text box. It is a dynamic text box (meaning it can change). I can't get it into the box to show it.

Logic is that the numbers can not be over 100 (as the app is designed for Grade 3's).

I will look at the links and let you know if I need help!!

Thanks;
Zach
