Game Design Document help

Mon, 18 Nov 2013 15:38:42 +0000

I have the idea for the game planned out already, and the assignment is that I have to write the first part of my Game Design Document and it needs to be 2-3 pages long. I prefer that it were three pages. I've looked all over the Internet, but haven't been able to find one that I believe will help me. Is there anything that anyone using this site knows that will help me?

Automatic Scrolling

Tue, 08 Jan 2008 00:45:31 +0000

Hey people. I was wondering how to make the view scroll to the top of the screen and then stop, display a message, and go to the next level. The game I'm making is called bold textShuriken Ninjabold text and the main problem is scrolling to the top of the screen, then stopping. I've checked a different game for an answer (bold text1945bold text) but got nothing. I want to do this using an object but if there is a way to code the room to do that then please tell me.

Help with simple collision error

Fri, 02 Nov 2007 12:46:12 +0000

HI,

I am am having trouble with a small game that i am working on. The problem lies with the collision of the bullet and the enemy. For some reason i can only get the enemy to delete when the collision is detected, if i place in the command to delete the curBullet when the collision is detected i recieve a memory access error and the program ends. I don't understand why the error occurs, i am assuming that i need to place the delete command in a different place but so far i have not been successful,

Thanks to all

Rewind bug

Wed, 24 Oct 2007 06:33:05 +0000

Ok, I've come across a weird bug with the Rewind function in my game and I don't quite get how it's going wrong.

Anyway, the problem is that when I have more than one enemy and then try to Rewind them, they all kind of join together position-wise and then start switching between each others' positions in their Rewind data. Basically, for each of them their data for where they have been is getting screwed up somehow. By outputting the Y position stored in the first part of the array at different intervals, I've pinpointed the code that's the problem, although I was pretty sure it was that anyway.

Here's the code of what I do to all the enemies each loop:

//here we adjust the enemies- all the AI stuff + scroll and check for hit with player for (g = 0; g < 100; g++) { if (enemy[g].used) { enemy[g].coll = false; if (tim_body.hitTest(enemy[g].sp)) { if (hurt == 0) { health -= 5; jumping = true; dir = enemy[g].dir; yVel = 10; xVel = 15 * dir; hurt = 50; } coll = true; enemy[g].coll = true; } if (tRewind > 500) { enemy[g].Rewind(tRewind); } if (tPause < 250) { enemy[g].walk(lvl); if (tRewind < 500) { enemy[g].memorise(g); //trace("Post-Memory" + g + ":" + enemy[0].rY[249]); } } enemy[g].sp._x += XOff; enemy[g].sp._y += YOff; enemy[g].XOff += XOff; enemy[g].YOff += YOff; } }

And here's the Enemy class which has the function that's the problem, memorise():

class Enemies { public var sp:MovieClip, used:Boolean, eType:Number, XOff:Number = 0, YOff:Number = 0; public var j:Number = 0; public var coll:Boolean = false; private var rX:Array = new Array(250), rY:Array = new Array(250), rF:Array = new Array(250); private var rD:Array = new Array(250); private var dir:Number = -1; public function Enemies(eUsed, eSp, eeType) { this.used = eUsed; this.sp = eSp; this.eType = eeType; } public function walk(lvl) { if (lvl[int((this.sp._y - this.YOff) / 50)][int((this.sp._x + (30 * this.dir) - this.XOff) / 50)] < 9 && lvl[int((this.sp._y - this.YOff + this.sp._height) / 50)][int((this.sp._x + (30 * this.dir) - this.XOff) / 50)] >= 9) { if (!this.coll) { this.sp._x += 3 * this. dir; } }else { this.dir = -this.dir; } this.sp._xscale = 100 * this.dir; } public function memorise() { for (j = 0; j < 249; j++) { this.rX[j] = this.rX[j + 1]; this.rY[j] = this.rY[j + 1]; this.rF[j] = this.rF[j + 1]; this.rD[j] = this.rD[j + 1]; } this.rX[249] = this.sp._x - this.XOff; this.rY[249] = this.sp._y - this.YOff; this.rF[249] = this.sp._currentframe; this.rD[249] = this.dir; } public function Rewind(tRewind) { this.sp._x = this.rX[tRewind - 501] + this.XOff; this.sp._y = this.rY[tRewind - 501] + this.YOff; this.sp.gotoAndStop(rF[tRewind - 501]); this.dir = this.rD[tRewind - 501]; } }

From what I was outputting with the trace right after running the enemy.memorise() function, I found that the same variable of one of the enemies was coming out different after running the memorise() function of the OTHER enemy. However, since I'm using "this" with all my references (except j), I don't see how this is happening.

I also outputted all of the previous Y positions of both enemies at one point, and got this:

0: 252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352 1: 252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352,252,352

You'll notice that both of the arrays are exactly the same (although considering the Rewind results I probably should have guessed that). It's almost as though the rY, rX and so on arrays are being static, but I didn't declare them that way so I don't see why they would be.

Anyway, any help on this would be appreciated.

Problem with collision in text game

Tue, 16 Oct 2007 13:57:41 +0000

hi,

I am having trouble with a text game I am working on. I am creating it using blitz basic.
the game is basically a space invaders clone.
i am going to paste my code below my question

heres my problem, i have created two type statements, one for bullets and one for enemies(blocks). i the used to seperate functions to create them both and draw them to the screen. I want to check for collisons between the two but when i try to check for any collision between the two i get a memory access violation so i am assuming that they are both not in existance at the same time? i know this is a really vague description but i am having trouble understanding the problem. Thank you for any help.

Flipping in AS

Thu, 27 Sep 2007 10:47:25 +0000

Well, I've come to working a bit more on the player animation, and as usual I've made the animation for one direction only. Natrually, my first impulse is to just horizontally flip the sprite when it needs to face the other direction. However, from what I've seen, it doesn't look like AS has any sort of "movieClip.flip" function or anything similar. I've tried duplicating all the frames and flipping them individually to get some animation for the other direction, but for some reason it's unaligning them on the X axis which makes the animation look weird.

So yeah, my question is, is there any easy way to flip a Movie Clip in AS?

palette fading to black and back again

Sun, 23 Sep 2007 12:46:30 +0000

Hi, I have been working through qbasic tutorials provided on petesqbsite (using freebasic though) and have been trying to work things out for myself rather than ask questions for every little thing, but I've finally hit a brick wall. One of the programs in the tutorials teaches about palettes and provides an example to fade the screen to black. I am trying to modify it so it fades to black, then back to the original color again. It works SOME of the time, but other times will not END or will suddenly switch to a random color after the fade-up (the fade to black works fine every time).
Can anybody see anything wrong with my code? I've also posted this on the freebasic forums, I think some of you guys use both, any help is much appreciated!

Compass for a text adventure game

Sun, 16 Sep 2007 16:33:20 +0000

Hi,
I'm working on a text adventure game at the moment, its in its very early stages but something I would like to add to it would be a "compass" of sorts that sits in the top right hand corner of the screen and depending on your actions and movements it changes the direction it points.
I can draw one using CIRCLE and LINE comands (it only has to point 4 directions) but I have the problem of refreshing it so it points a new direction. If I use CLS then redraw it then it clears all my previous text as well which is no good. I could draw a "black" line over the top of the unwanted 3 directions each time I want the compass to point somewhere new, but thats messy. Is there any way to clear a small section of the screen only, or un-draw a line that has been placed?
Any help is much appreciated, I know this is a proper noob question!
Thanks again

Help in Scripting- 2D game, overhead, Strafe feature

Fri, 14 Sep 2007 16:24:24 +0000

I have a script in Step event- take a step towards cursor x,y. This makes the
character always face the cursor, and strafing or moving in any other direction, the
character won't move in another direction. That's the major problem.

Like I said, I know the strafing code parameters, but with the face cursor in the
step event, the strafing thing won't work.
Thanks, have at it, and any replys please send them to the following:

thank you.

ActionScript Question

Thu, 13 Sep 2007 07:53:45 +0000

Ok. Firstly, I'm trying to declare a 2D array with all its values predetermined. However, trying to declare it with the following code seems to leave all the values as undefined. Anyone know what I'm doing wrong?

var lvl:Number = new Number((0,0,0,0,0,0,0,0,0,0,0), (0,0,0,0,0,0,0,0,0,0,0), (0,0,0,0,0,0,0,0,0,0,0), (0,0,0,0,0,0,0,0,0,0,0), (0,0,0,0,0,0,0,0,0,0,0), (0,0,0,0,0,0,0,0,0,0,0), (0,0,0,0,0,0,0,0,0,0,0), (0,0,0,0,0,0,0,0,0,0,0), (1,1,1,1,1,1,1,1,1,1,1));

Also, if I try to declare a class like this:

class Walls { }

I get an error message saying "Classes may only be defined in external ActionScript 2.0 class scripts." What does this mean?

Ok, so i made a game in .gmk format. I want to get it to .exe format so i can upload it to yoyogames. but i dont know how to exactly. I've tried simply saving it as a .exe (using default .exe settings or whatever) and putting it in a .zip folder. When i upload it to yoyogames it doesnt work. Is there a certain way to turn a .gmk into a .exe or do you have to do something more to get it to upload bacause thats my goal here

Is there a way, in code, to declare the transparent background color of sprites in Basic4GL?

F.e, if you do

print "hi." screen 13 print "hi" sleep end

It creates a new window .. and there is a command-prompt thingy left .. how do i make the command-thing go away?
