Hey guys, I can't seem to get TFormNormal to return any results other than -1 I'm trying to get cube1's normal of cube2 Import sidesign.minib3d Graphics3D(800,600,0,2) Global cam:TCAmera = CreateCamera() PositionEntity cam,0,0,-10 Global light:TLight = CreateLight() Global cube1:TMesh = CreateCube() Global cube2:TMesh = CreateCube() PositionEntity cube2,0,5,0 Global pointX:Float Global pointY:Float Global pointZ:Float Global vectX:Float Global vectY:Float Global vectZ:Float Global normX:Float Global normY:Float Global normZ:Float Global dpitch:Float Global dyaw:Float SetBlend(ALPHABLEND) While Not KeyHit(KEY_ESCAPE) TFormPoint 0,0,0,cube1,cube2 pointX = TFormedX() pointY = TFormedY() pointZ = TFormedZ() TFormVector 0,0,0,cube1,cube2 vectX = TFormedX() vectY = TFormedY() vectZ = TFormedZ() TFormNormal 0,0,0,cube1,cube2 normX = TFormedX() normY = TFormedY() normZ = TFormedZ() dpitch = DeltaPitch(cube1,cube2) dyaw = DeltaYaw(cube2,cube1) If KeyDown(KEY_LEFT) Then MoveEntity(cube2,-0.5,0,0) If KeyDown(KEY_RIGHT) Then MoveEntity(cube2,0.5,0,0) If KeyDown(KEY_UP) Then MoveEntity(cube2,0,0.5,0) If KeyDown(KEY_DOWN) Then MoveEntity(cube2,0,-0.5,0) If KeyDown(KEY_A) Then MoveEntity(cube1,-0.5,0,0) If KeyDown(KEY_D) Then MoveEntity(cube1,0.5,0,0) If KeyDown(KEY_W) Then MoveEntity(cube1,0,0.5,0) If KeyDown(KEY_S) Then MoveEntity(cube1,0,-0.5,0) If KeyDown(KEY_Z) Then TurnEntity(cube1,0,-1,0) If KeyDown(KEY_X) Then TurnEntity(cube1,0,1,0) If KeyDown(KEY_C) Then TurnEntity(cube2,0,-1,0) If KeyDown(KEY_V) Then TurnEntity(cube2,0,1,0) RenderWorld BeginMax2d() DrawText "PX: " + pointx,0,0 DrawText "PY: " + pointy,0,12 DrawText "PZ: " + pointz,0,24 DrawText "VX: " + vectX,0,48 DrawText "VY: " + vectY,0,60 DrawText "VZ: " + vectZ,0,72 DrawText "NX: " + normX,0,96 DrawText "NY: " + normY,0,108 DrawText "NZ: " + normZ,0,120 DrawText "EX: " + EntityX(cube2),0,144 DrawText "EY: " + EntityY(cube2),0,156 DrawText "EZ: " + EntityZ(cube2),0,168 DrawText "DP: " + dpitch,0,192 DrawText "DY: " + dyaw,0,204 EndMax2d() Flip Cls Wend |

It's not clear what you are trying to do here. The result of TFormNormal applied to 0,0,0 is not defined. In real Blitz3D it would produce NaN rather than -1. You can find a description of TFormNormal in the Blitz3D online manual http://blitzbasic.com/b3ddocs/command.php?name=tformnormal&ref=goto Scroll down to the comments to see what it really does. |
