Animated Texture Demo

Virion · Post by **Virion** » Sat Jul 19, 2008 9:00 am

i realized that I didn't touch c++ for a long time (and almost forget everything)... so i playing around with it.

http://www.zerocore.net/demo.zip

I think we can also make animated particles? I will check it out soon.

p/s. i'm currently an art student so hardly got time for programming... damn i've forgotten most of the things about c++!

add:

Code: Select all

#include <irrlicht.h>
#include "main.h"

using namespace irr;

using namespace core;
using namespace scene;
using namespace video;
using namespace io;
using namespace gui;

u32 oldNow;
u32 time;
u32 now;
u32 elapsed;

int main()
{
    IrrlichtDevice *device = createDevice(EDT_OPENGL, dimension2d<s32>(512, 512), 32, false, false, false, 0);
    device->setWindowCaption(L"Irrlicht Animated Texture Demo");

    IVideoDriver* driver = device->getVideoDriver();
    ISceneManager* smgr = device->getSceneManager();
    IGUIEnvironment* guienv = device->getGUIEnvironment();

    oldNow = device->getTimer()->getRealTime();
    time = 0;

    int i = 1;
    ITexture* img[i];

    img[1] = driver->getTexture("beast1.jpg");
    img[2] = driver->getTexture("beast2.jpg");
    img[3] = driver->getTexture("beast3.jpg");
    img[4] = driver->getTexture("beast4.jpg");
    img[5] = driver->getTexture("beast5.jpg");

    IAnimatedMesh* mesh = smgr->getMesh("beast.b3d");
    IAnimatedMeshSceneNode* node = smgr->addAnimatedMeshSceneNode(mesh);
    node->setMaterialFlag(EMF_LIGHTING,false);
    node->setFrameLoop(1, 25);

    smgr->addCameraSceneNode(0, vector3df(100,100,-150), vector3df(0,5,0));

    while(device->run())
    {
        now = device->getTimer()->getRealTime();
        elapsed = now - oldNow;
        oldNow = now;
        time += elapsed;

        if (time<1000)
        {
            i = 1;
        }
        if (time>1000)
        {
            i = 2;
        }
        if (time>2000)
        {
            i = 3;
        }
        if (time>3000)
        {
            i = 4;
        }
        if (time>4000)
        {
            i = 5;
        }
        if (time>5000)
        {
            time = 0;
        }

        node->setMaterialTexture( 0,img[i]);


        driver->beginScene(true, true, SColor(255,100,101,140));

        smgr->drawAll();
        guienv->drawAll();
        driver->endScene();

    }
    device->drop();
    return 0;

}

Thanks for sharing, but this might be better in Code Snippets than Project Announcements.

dude, ill really like to see the source, that could be useful to animate sprites! or play animations on planes, could you share the code ?

Virion · Post by **Virion** » Sat Jul 19, 2008 10:04 pm

ok... maybe someone should move this thread to code snippet.

code added at the first post.

Sorry if I came across as negative; I'm sure this is great stuff.

the code could be expanded further and enhanced by someone who has more experience in c++ than an art student.

well, just a little enhancement so you can use any amount of textures you want to

:

Code: Select all

#include <irrlicht.h>
#include "main.h"

using namespace irr;

using namespace core;
using namespace scene;
using namespace video;
using namespace io;
using namespace gui;

u32 oldNow;
u32 time;
u32 now;
u32 elapsed;

int main(){
    IrrlichtDevice *device = createDevice(EDT_OPENGL, dimension2d<s32>(512, 512), 32, false, false, false, 0);
    device->setWindowCaption(L"Irrlicht Animated Texture Demo");

    IVideoDriver* driver = device->getVideoDriver();
    ISceneManager* smgr = device->getSceneManager();
    IGUIEnvironment* guienv = device->getGUIEnvironment();

    oldNow = device->getTimer()->getRealTime();
    time = 0;

    array<ITexture*> img;

    img.push_back(driver->getTexture("beast1.jpg"));
    img.push_back(driver->getTexture("beast2.jpg"));
    img.push_back(driver->getTexture("beast3.jpg"));
    img.push_back(driver->getTexture("beast4.jpg"));
    img.push_back(driver->getTexture("beast5.jpg"));
    // you can add as many textures as you want

    IAnimatedMesh* mesh = smgr->getMesh("beast.b3d");
    IAnimatedMeshSceneNode* node = smgr->addAnimatedMeshSceneNode(mesh);
    node->setMaterialFlag(EMF_LIGHTING,false);
    node->setFrameLoop(1, 25);

    smgr->addCameraSceneNode(0, vector3df(100,100,-150), vector3df(0,5,0));

    node->setMaterialTexture( 0,img[0]);
    u32 i = 1; // set to 1 because we already used texture at index 0

    while(device->run()){
        now = device->getTimer()->getRealTime();
        elapsed = now - oldNow;
        if(elapsed > 1000){
          node->setMaterialTexture( 0,img[i++]);
          i = i % img.size();
          oldNow = now;
        }

        driver->beginScene(true, true, SColor(255,100,101,140));

        smgr->drawAll();
        guienv->drawAll();
        driver->endScene();

    }
    device->drop();
    return 0;

}

Surely you can already do this with the TextureAnimator.....

omg i didnt know that

Thank you very much for that Virion, it's very helpful to me. It's just straight forward and gives you animated textures, not run around with NO instructions or directions for beginners like what many other people post. That was very generous of you.

I see JP said that there's a texture animator, but I've been searching and searching and I'm Finding NOTHING. I'm just fed up with that with Irrlicht, yeah I'm a newbie, but it's discouraging how hard it is to find info and how to implement certain mainstream stuff. I searched for animated textures in Ogre and found several straight forward directions to get it right away. Seriously, Irrlicht is harder than Orge. Thanks for this straight forward approach Virion. Irrlicht has much much less support than Ogre- and it's trumpeted as the simpler and more straight forward of the 2, gets me really annoyed at how lacking the support is!!! Could you more experienced guys help out the newbies in a little more straight forward way please. Post some links, leave some more hints so we could search for ourselves, not just dry half line answers that we can get nothing from, and only make sense to the experienced users. Thank you Virion.

The support is all about community, Irrlich community is well.. a bit quiet, but still i hope it grows itself as the Irrlicht Engine itself has been great finding to me.

The texture animator is part of the Irrlicht SDK, its use is shown in the Demo, and the API docs contain all necessary stuff to learn about other use. Please learn to use the exsiting documentation and complain only about lack of it if there's really a lack!
