Directx 9 light material

lonol15

Hallo,
ich will ein Licht initialisieren, jedoch leuchtet es seltsamerweise nur mit folgenden Einstellungen:

light.Diffuse.r  = -107374176.0f;
	light.Diffuse.g  = -107374176.0f;
	light.Diffuse.b  = -107374176.0f;
	light.Diffuse.a  = -107374176.0f;

Wobei es doch eigentlich mit diesen Einstellungen leuchten sollte:

light.Diffuse.r  = 1.0f;
	light.Diffuse.g  = 1.0f;
	light.Diffuse.b  = 1.0f;
	light.Diffuse.a  = 1.0f;

Vermutlich ist es ein total dämlicher kleiner Fehler, aber ich komm einfach nicht auf die Lösung. Hier noch Teile von dem restlichen Code:

d3dDevice->SetFVF(D3DFVF_XYZ | D3DFVF_NORMAL | D3DFVF_TEX1 );

	d3dDevice->SetRenderState(D3DRS_LIGHTING, TRUE);
	d3dDevice->SetRenderState(D3DRS_CULLMODE, D3DCULL_NONE);
	d3dDevice->SetRenderState(D3DRS_DITHERENABLE, TRUE);
	d3dDevice->SetRenderState(D3DRS_ZENABLE,D3DZB_TRUE);

	D3DXMATRIX view;
	D3DXMATRIX world;
	D3DXMATRIX projection;

	D3DXMatrixLookAtLH(&view, &D3DXVECTOR3(0.0f,0.0f,3.0f),&D3DXVECTOR3(0.0f,0.0f,0.0f),&D3DXVECTOR3(0.0f,1.0f,0.0f));
	D3DXMatrixPerspectiveFovLH(&projection, D3DXToRadian(45),(float)width/(float)height,1.0f,100.0f);

	d3dDevice->SetTransform(D3DTS_VIEW, &view);
	d3dDevice->SetTransform(D3DTS_PROJECTION, &projection);

D3DLIGHT9 light;

	light.Type = D3DLIGHT_POINT;

	light.Diffuse.r  = -107374176.0f;
	light.Diffuse.g  = -107374176.0f;
	light.Diffuse.b  = -107374176.0f;
	light.Diffuse.a  = -107374176.0f;

	light.Position.x = 0.0f;
	light.Position.y = 1.0f;
	light.Position.z = 1.0f;

	light.Range = 100.0f;
	light.Attenuation0 = 0.0f;
	light.Attenuation0 = 0.025f;
	light.Attenuation0 = 0.0f;

	d3dDevice->SetLight(0,&light);

	d3dDevice->LightEnable(0,TRUE);
	d3dDevice->SetRenderState(D3DRS_AMBIENT, D3DCOLOR_XRGB(0,0,0));

D3DMATERIAL9 mat;

	mat.Diffuse.r = 1.0f;
	mat.Diffuse.g = 1.0f;

	mat.Specular.r = 1.0f;
	mat.Specular.g = 1.0f;
	mat.Specular.b = 1.0f;
	mat.Specular.a = 1.0f;
	mat.Power = 100.0f;

	mat.Emissive.r = 0.0f;
	mat.Emissive.g = 0.0f;
	mat.Emissive.b = 0.0f;
	mat.Emissive.a = 0.0f;

	d3dDevice->SetMaterial(&mat);

	d3dDevice->SetSamplerState(0, D3DSAMP_MINFILTER, D3DTEXF_LINEAR);
	d3dDevice->SetSamplerState(0, D3DSAMP_MAGFILTER, D3DTEXF_LINEAR);
	d3dDevice->SetSamplerState(0, D3DSAMP_MIPFILTER, D3DTEXF_LINEAR);

	d3dDevice->SetTexture(0, texture);

	int zoomf = 4;

	Vertex fd[3];	
	fd[0].position = D3DXVECTOR3(0.0f,1.0f,0.0f);
	fd[1].position = D3DXVECTOR3(1.0f,-1.0f,0.0f);
	fd[2].position = D3DXVECTOR3(-1.0f,-1.0f,0.0f);

	fd[0].tposition = D3DXVECTOR2(0.5f*zoomf,1.0f*zoomf);
	fd[1].tposition = D3DXVECTOR2(1.0f*zoomf,0.0f*zoomf);
	fd[2].tposition = D3DXVECTOR2(0.0f*zoomf,0.0f*zoomf);

	fd[0].nposition.x = 0.0f;
	fd[0].nposition.y = 0.0f;
	fd[0].nposition.z = 1.0f;

	fd[1].nposition.x = 0.0f;
	fd[1].nposition.y = 0.0f;
	fd[1].nposition.z = 1.0f;

	fd[2].nposition.x = 0.0f;
	fd[2].nposition.y = 0.0f;
	fd[2].nposition.z = 1.0f;

	d3dDevice->DrawPrimitiveUP(D3DPT_TRIANGLELIST, 1, fd, sizeof(Vertex));

	d3dDevice->SetTexture(0, NULL);

Ich freu mich auf eure Antworten
