Irrlicht Engine

Posted: **Mon May 31, 2010 7:17 pm**

I was re-coding my full game and i found that file , that I made since a really long time, in a hidden folder: CTransition.h, It is working well and I wanted to share it to the community.

Really simple code, I use it to make image transition between different scenes, (ie: for loading screen, for Intro-screen, etc...).

Here are some screens and a demo:
REMOVED IMAGES

Demo: (about 2mb)
REMOVED UNTIL FIX
FIXED RELEASE : http://www.mediafire.com/?wuymwymmjjn

How to use :

Code: Select all

 
///CALLING A NEW TRANSITION

    CTransition* Transit = new CTransition(device);

    Transit->CutScene(device->getVideoDriver()->getTexture("INTRO1.jpg"),
                                            0,SColor(0,255,255,0)); ///YELLOW TRANSIT
    Transit->CutScene(device->getVideoDriver()->getTexture("INTRO2.jpg"),
                                            0,SColor(0,0,255,255)); ///CYAN TRANSIT
    delete Transit;

    ///END OF TRANSITION

This is extremely simple to use, you simply call CutScene(), it has 3 parameters:
1-The texture, or image of background.
2-The time of showing image.
3-The color of fading.

You could also use the specific functions as FadeIn(), FadeOut() or Attendre(), to manually compose different transitions. Im used to add a load function to my loading transitions.

Enjoy it and thanks for commenting.

Neither the demo or recompilled source want to work. It seems that there're updating problems ( when I move the window with mouse it actually updates!

), but I can't check it out and fix it at the moment(got illness, problems with throat and lungs.. Laptop FTW!

).. Hope you can fix it yourself it would be really nice to have it in my project

How come? I work perfectly with me, can you give more details? What computer are u using and which Irrlicht version you using?

It seems that there're updating problems ( when I move the window with mouse it actually updates! )

You mean, it does not update. Actually, when im trying to move the window, it simply stop fading, and when i release it, it continues fading.

If its always stuck to the first loop, simply change FAC_ALPHA value to a lower value.

If it's not what you mean, then i really dont understand what is the problem.

thanks for commenting,
and btw, im sorry for your illness.

OHH, I know what you mean loool,
Im gonna fix that.

(Its because your computer is to fast hehehe)

Code: Select all

 Current_Alpha += round32(TimeCalculator()*FAC_ALPHA);

this is equaling almost 0 because TimeFactor is very low, and by rounding it it gives so 0 so it looks like theres no updating...

Well, maybe my computer is a little too fast, I dunno ( 3,6GHz P4 HT cpu on PC and dual core 3.2GHz on Laptop

), but the main reason it is it won't update automatically. It works with short-moves around the screen, it actually changes between transits also

Even multiplying the time calculator won't help, dah

Ok i have fixed it.
Actually it was really bad coded, but the general base was there so I didnt change everything.
FIXES (2 JUNE 2010):
-1.Changed

Code: Select all

typedef unsigned short int E_SHORT;

to

Code: Select all

typedef signed short int E_SHORT;

Well, without this it was always restarting the transition, because when Current_ALPHA < 0, it gets to 65536 (unsigned int) and restarts everything.

-2.Added

Code: Select all

float A = NO_ALPHA;

and changed this :

Code: Select all

Current_Alpha= round32(TimeCalculator()*FAC_ALPHA);

to this :

Code: Select all

A += (TimeCalculator()*FAC_ALPHA);
        Current_Alpha = round32(A);

THATS IT!
Now i still need some testers for this... because i have 1 computer working for now and its a P3 256mb ram with integrated graphic card (WORST THING FOR PROGRAMMING LOL) that i didnt even buyed (someone gave me because it was to old, I just dont know why I even thinked about learning programming LOOL), so yes, Murloc992, your computer is very fast.

I re-chekd everything and it should work...

Waiting your comments and thanks for reporting those issues.

Working perfect now.

Really appreciate what you've done.

Do you need credits if I use it? Just wondering.

Posted: **Wed Jun 02, 2010 4:41 pm**

Thanks!

Well, your not obligated...But if you want ill appreciate it and if you are using it in a project, just PM me I would like to see how did you implement it.
