Tutorial - Setup Horde with SDL

Here is a small example on how to use Horde with sdl. Its a simple frame that closes when the x on the window is clicked.

Simple SDL Frame

#include <iostream> #include <Horde3D.h> #include <SDL.h> int main(int argc, char* args[]){ //Creates are bool value for the while loop. bool running = true; //Inits sdl with only the video extention. SDL_Init(SDL_INIT_VIDEO); //Sets are window Caption SDL_WM_SetCaption("Simple SDL Frame",NULL); //Sets the sdl video mode width and height as well has creates are opengl context. SDL_SetVideoMode(800,600,32,SDL_OPENGL); //Creates Are Event Reciver SDL_Event event; //Inits Horde3D Horde3D::init(); //Sizes the Horde3D View Horde3D::resize( 0, 0, 800, 600 ); // Add pipeline resource ResHandle pipeRes = Horde3D::addResource( ResourceTypes::Pipeline, "standard.pipeline.xml", 0 ); // Add model resource ResHandle modelRes = Horde3D::addResource( ResourceTypes::SceneGraph, "character.scene.xml", 0 ); // Add animation resource ResHandle animRes = Horde3D::addResource( ResourceTypes::Animation, "walk.anim.xml", 0 ); // Load added resources Horde3DUtils::loadResourcesFromDisk( "" ); // Add model to scene model = Horde3D::addNodes( RootNode, modelRes ); // Apply animation Horde3D::setupModelAnimStage( model, 0, animRes, "" ); // Add light source NodeHandle light = Horde3D::addLightNode( RootNode, "Light1", 0, "LIGHTING", "SHADOWMAP" ); // Set light position and radius Horde3D::setNodeTransform( light, 0, 20, 0, 0, 0, 0, 1, 1, 1 ); Horde3D::setLightParam( light, LightNodeParams::Radius, 50.0f ); // Add camera cam = Horde3D::addCameraNode( RootNode, "Camera", pipeRes ); // Our While loop while(running == true){ static float t = 0; // Increase animation time t = t + 10.0f * (1 / 60); //Checks if there is a event that needs processing if(SDL_PollEvent(&event)){ //Checks to see if the event is a SDL_QUIT*x on the window is clicked. if(event.type == SDL_QUIT){ //Sets the while loop to false and ends program running = false; } } // Play animation Horde3D::setModelAnimParams( model, 0, t, 1.0f ); // Set new model position Horde3D::setNodeTransform( model, t * 10, 0, 0, // Translation 0, 0, 0, // Rotation 1, 1, 1 ); // Scale // Render scene Horde3D::render( cam ); } //Releases the Horde3D Engine Horde3D::release(); //Releases SDL and quits are program SDL_Quit(); }
