problems with x files?
Blitz3D Forums/Blitz3D Programming/problems with x files?
| ||
| I looked in the code archives to try to find a way so that my program will create random meshes and save them together as a single x file. What happens is instead of saving them together, the program resaves the previous mesh as the newer x file, so all I get is one single object in the x file instead of all the meshed created. Here is the code. Graphics3D 800,600 light=CreateLight() camera=CreateCamera() SetBuffer BackBuffer() t#=1.0 t1=OpenFile(t# + ".txt") ;make a text file called bogus and place it in the directory t2=OpenFile(t#+ ".txt") t3=WriteFile("completelevel.x") ;;start off with a random mesh SeedRnd(MilliSecs()) If Rnd(5)>-1 And Rnd(5)<2 Then mesh=CreateCube() If Rnd(5)>1 And Rnd(5)<3 Then mesh=CreateSphere() If Rnd(5)>2 And Rnd(5)<4 Then mesh=CreatePlane() If Rnd(5)>3 And Rnd(5)<5 Then mesh=CreateCylinder() If Rnd(5)>4 And Rnd(5)<6 Then mesh=CreateCone() Function SaveMeshX(mesh,file$) ;single surface at the moment cnt=CountSurfaces(mesh) If cnt=0 Then Return ;TODO Multi surface support surf=GetSurface(mesh,1) out=WriteFile(file$) WriteLine out,"xof 0302txt 0064" WriteLine out,"" WriteLine out,"Header {" WriteLine out," 1;" WriteLine out," 0;" WriteLine out," 1;" WriteLine out,"}" WriteLine out,"" WriteLine out,"Frame frm_Scene_Root {" WriteLine out," FrameTransformMatrix {" WriteLine out," 1.000000,0.000000,0.000000,0.000000," WriteLine out," 0.000000,1.000000,0.000000,0.000000," WriteLine out," 0.000000,0.000000,1.000000,0.000000," WriteLine out," 0.000000,0.000000,0.000000,1.000000;" WriteLine out,"}" WriteLine out,"" name$=EntityName$(mesh) If name$="" Then name$="Unknown" WriteLine out,"Frame frm_"+name$+" {" WriteLine out," FrameTransformMatrix {" WriteLine out," 1.000000,0.000000,0.000000,0.000000," WriteLine out," 0.000000,1.000000,0.000000,0.000000," WriteLine out," 0.000000,0.000000,1.000000,0.000000," WriteLine out," 0.000000,0.000000,0.000000,1.000000;" WriteLine out,"}" WriteLine out,"" WriteLine out," Mesh frm_"+name$+" {" WriteLine out,CountVertices(surf)+";" For a=0 To CountVertices(surf)-1 WriteLine out,VertexX(surf,a)+";"+VertexY(surf,a)+";"+VertexZ(surf,a)+";," Next WriteLine out,"" WriteLine out," "+CountTriangles(surf)+";" For a=0 To CountTriangles(surf)-1 in1=TriangleVertex(surf,a,0) in2=TriangleVertex(surf,a,1) in3=TriangleVertex(surf,a,2) ln$=" 3;"+in1+","+in2+","+in3+";" If a=CountTriangles(surf)-1 Then ln$=ln$+";" Else ln$=ln$+"," WriteLine out,ln$ Next WriteLine out,"" WriteLine out,"MeshMaterialList {" WriteLine out,"1;" WriteLine out,"1;" WriteLine out,"0;;" WriteLine out,"" WriteLine out,"Material {" WriteLine out," 1.000000,1.000000,1.000000,1.000000;;";rgba WriteLine out," 1.000000;" WriteLine out," 0.500000,0.500000,0.500000;;" WriteLine out," 0.000000,0.000000,0.000000;;" WriteLine out,"}" WriteLine out,"}" WriteLine out,"" WriteLine out,"MeshNormals {" WriteLine out,CountVertices(surf)+";" For a=0 To CountVertices(surf)-1 WriteLine out,VertexNX(surf,a)+";"+VertexNY(surf,a)+";"+VertexNZ(surf,a)+";," Next WriteLine out," "+CountTriangles(surf)+";" For a=0 To CountTriangles(surf)-1 in1=TriangleVertex(surf,a,0) in2=TriangleVertex(surf,a,1) in3=TriangleVertex(surf,a,2) ln$=" 3;"+in1+","+in2+","+in3+";" If a=CountTriangles(surf)-1 Then ln$=ln$+";" Else ln$=ln$+"," WriteLine out,ln$ Next WriteLine out,"}" WriteLine out,"" WriteLine out,"MeshTextureCoords {" WriteLine out,CountVertices(surf)+";" For a=0 To CountVertices(surf)-1 ln$=VertexU(surf,a)+";"+VertexV(surf,a)+";" If a=CountVertices(surf)-1 Then ln$=ln$+";" Else ln$=ln$+"," WriteLine out,ln$ Next WriteLine out," }" WriteLine out," }" WriteLine out," }" WriteLine out,"}" CloseFile out End Function While Not KeyDown(1) file$=(t#+".txt") If KeyDown(57) Then End If KeyHit(28) SaveMeshX(mesh,file$) EndIf If t1 And t2 And t3 Then While Not Eof(t1):WriteLine(t3,ReadLine$(t1)):Wend While Not Eof(t2):WriteLine(t3,ReadLine$(t2)):Wend EndIf RenderWorld UpdateWorld Text 300,200, "Press Enter to create another model" Text 300,220, "Press Space to save and exit" Text 300,240, "T#" Text 340,240,t# Flip Wend End |

| I don't know if this helps but both t1 and t2 are using the same filename thus both are referencing the same file. |
