    Problem of shadow in game with C++ ?

    in Programming

    Posted

    I have a problem the shadow so i have coded in C++ but it doesn't work, how to resolve it, please ?

    The code here : 

    #include "App.h"

using namespace Leadwerks;

App::App() : window(NULL), context(NULL), world(NULL), camera(NULL) {}

App::~App() { delete world; delete window; }

//Camera storage
Vec3 camRotation;
Vec2 centerMouse;
Vec2 mouseDifference;
float mouseSensitivity;

//Player
Model* playerMesh;
Entity* player;
Model* tpsSphere;

//Speeds
Vec3 playerMovement;
float moveSpeed;
float strafeSpeed;

//jump and crouch
float jumpForce;
float tempJumpForce;
bool crouched;
float playerHeight;
float playerCrouchHeight;

//angles
float cameraTopAngle;
float cameraBottomAngle;
float camSmoothing;

//TPS controls
Pivot* fpsPivot;
Pivot* tpsPivot;
float maxCamOffset;
float minCamOffset;
Vec3 oldCamPos;




bool App::Start()
{
	//Create a window
	window = Window::Create("_9_TPSController", 200, 0, 1024,768);
		
	//Create a context
	context = Context::Create(window);
	
	//Create a world
	world = World::Create();
	
	//Create a camera
	camera = Camera::Create();
	camera->Move(0,2,-5);

	/*light = PointLight::Create();
	light->SetPosition(0, 100, 0);
	light->SetRange(1);*/

	
	//Hide the mouse cursor
	window->HideMouse();
	
	Map::Load("Maps/my_map.map");
	
	//Move the mouse to the center of the screen
	centerMouse = Vec2(context->GetWidth()/2,context->GetHeight()/2 );
	window->SetMousePosition(centerMouse.x, centerMouse.y);
	mouseSensitivity =		15;

	//Create the player
	player = Pivot::Create();
	player->SetPosition(0,4,0);
    player->SetMass(5);
    player->SetPhysicsMode(Entity::CharacterPhysics);
	player->SetShadowMode(Light::Static | Light::Dynamic);

	//Create camera pivot
	fpsPivot = Pivot::Create();
	tpsPivot = Pivot::Create();

	//Create a visible mesh
	playerMesh = Model::Cylinder(16,player);
	playerMesh->SetPosition(0,1,0);
    playerMesh->SetScale(1,2,1);
	
	//Set some variables
	moveSpeed			= 6;
	strafeSpeed			= 4;
	crouched			= false;
	playerHeight		= 1.8;
	playerCrouchHeight	= 0.8;
	jumpForce			= 6;
	cameraTopAngle		= -45;
	cameraBottomAngle	= 80;
	camSmoothing		= 8.0;

	//Tps camera
	maxCamOffset = -8.0;
	minCamOffset = 1.5;

	return true;
}

bool App::Loop()
{
	//Close the window to end the program
	if (window->Closed()||window->KeyHit(Key::Escape)) return false;
    
	//Get the mouse movement
	Vec3 currentMousePos = window->GetMousePosition();
	mouseDifference.x = currentMousePos.x - centerMouse.x;
	mouseDifference.y = currentMousePos.y - centerMouse.y;

	//Adjust and set the camera rotation
	float tempX = camRotation.x + (mouseDifference.y / mouseSensitivity);
	if(tempX > cameraTopAngle && tempX < cameraBottomAngle )
		camRotation.x = tempX;
	camRotation.y += mouseDifference.x / mouseSensitivity;
	fpsPivot->SetRotation(camRotation);
	window->SetMousePosition(centerMouse.x, centerMouse.y);

	//Player Movement
	playerMovement.x = (window->KeyDown(Key::D) - window->KeyDown(Key::A))	* Time::GetSpeed() * strafeSpeed;
	playerMovement.z = (window->KeyDown(Key::W) - window->KeyDown(Key::S))	* Time::GetSpeed() * moveSpeed;
	
	// Check for jumping
	tempJumpForce = 0;
	if(window->KeyHit(Key::Space) && !(player->GetAirborne()) )
			tempJumpForce = jumpForce;

	// Check for crouching
	if(window->KeyHit(Key::C))
		crouched = !crouched;

	//Position camera at correct height and playerPosition
	player->SetInput(camRotation.y, playerMovement.z, playerMovement.x, tempJumpForce * Time::GetSpeed(), crouched, 1);

	//Store player some information
	Vec3 tempFpsPos = fpsPivot->GetPosition();
	Vec3 playerPos = player->GetPosition();
	playerPos.y += (crouched ? playerCrouchHeight : playerHeight);
	tempFpsPos.y = Math::Curve(playerPos.y, tempFpsPos.y, camSmoothing * Time::GetSpeed());
	tempFpsPos = Vec3(playerPos.x, tempFpsPos.y ,playerPos.z);
	fpsPivot->SetPosition(tempFpsPos);

	//Position and Rotate the camera to FPS pivot
	camera->SetPosition(fpsPivot->GetPosition());
	camera->SetRotation(fpsPivot->GetRotation());

	//Calculate the furthest TPS pivot position
	tpsPivot->SetPosition(fpsPivot->GetPosition());
	tpsPivot->SetRotation(fpsPivot->GetRotation());
	tpsPivot->Move(0, 0, maxCamOffset, false);
	camera->SetPosition(tpsPivot->GetPosition());

	//Use a pick to determine where the camera should be
	PickInfo pick;
	if(world->Pick(fpsPivot->GetPosition(), tpsPivot->GetPosition(), pick, 0, true ))
	{
		//Store distance
		float distance = fpsPivot->GetPosition().DistanceToPoint(pick.position);
		printf((String(distance) + "\n").c_str());

		//If the tps distance is to small, we switch to FPS view
		if(distance < minCamOffset)
		{
			camera->SetPosition(fpsPivot->GetPosition());
		}
		else
		{
			camera->SetPosition(pick.position);
		}
	}
	else
	{
		camera->SetPosition(tpsPivot->GetPosition());
	}

	Time::Update();
	world->Update();
	world->Render();

	context->Sync(true);

	return true;
}

    The problem here is ==> player->SetShadowMode(Light::Static | Light::Dynamic); ... it is activated but it doesn't work for shadow as dynamic...

     

    Here it is screenshot for result :

    3 or 4 game sample as complete

    in Suggestion Box

    Posted

    We need some game sample made by Leadwerks as "complete" and "real" programming for 2D game c++ : 2d platform and top-down style; 3D game c++ : FPS and TPS style for learning way and very good for beginner and advanced :)

    What  do you think of that ?
