| I have make a special orbital gravity for some planets of my project Galaxang . Here I post a simple code , the same in Galaxang , which has thrown the mondial FPS gaming into the cosmos ! http://prymprog.wikeo.net - Galaxang46 Look at this chunk code ( it uses "EntityParent" and "AlignToVector" ) -------- ;;;; ;;;; orbital pivot demo ;;;; Global mouse_move_speed# = 0.25 Global GW% = 800 , GH% = 600 , type_ellipsoide% = 1 Global spaceplanet% = 0 , x% = -2 , y% = -2 , z% = -2 Global parentplayer0% = 0 , player0% = 0 , camera% = 0 Global pivotplanete4% = 0 , pivotorbiplanete4% = 0 Global planete4% = 0 , textureplanete4% = 0 , rndscale% = 0 Global mvx% = 0 , mvz% = 0 , vitesse% = 10 Global deplacy# = 0.0 , deplacx# = 0.0 Global campitch# = 0.0 , camyaw# = 0.0 , camroll# = 0.0 Global oldpitch# = 0.0 , oldyaw# = 0.0 , oldroll# = 0.0 Graphics3D GW , GH , 32 , 2 textureplanete4 = CreateTexture ( 32 , 32 ) SetBuffer TextureBuffer ( textureplanete4 ) ClsColor 100 , 110 , 130 Color 200 , 190 , 180 Cls Text 0 , 0 , "++++" Text 0 , 8 , "++++" Text 0 , 16 , "++++" Text 0 , 24 , "++++" SetBuffer BackBuffer ( ) ;player parentplayer0 = CreatePivot ( ) player0 = CreateSphere ( ) EntityRadius player0 , 100 EntityType player0 , type_ellipsoide ScaleEntity player0 , 10 , 10 , 10 camera = CreateCamera ( player0 ) CameraViewport camera , 0 , 0 , GW , GH PositionEntity player0 , 0 , 0 , -5000 ;scene For x = -2 To 2 Step 4 For y = -2 To 2 Step 4 For z = -2 To 2 Step 4 rndscale = Rand ( 5 , 30 ) spaceplanet = CreateSphere ( ) ScaleEntity spaceplanet , 10 * rndscale , 10 * rndscale , 10 * rndscale EntityColor spaceplanet , Rand ( 100 , 150 ) , Rand ( 50 , 200 ) , Rand ( 50 , 250 ) PositionEntity spaceplanet , 100 * x * Rand ( 5 , 20 ) , 100 * y * Rand ( 5 , 20 ) , 100 * z * Rand ( 5 , 20 ) Next : Next : Next ;planete4 pivotplanete4 = CreatePivot ( ) PositionEntity pivotplanete4 , 0 , 0 , 0 pivotorbiplanete4 = CreatePivot ( pivotplanete4 ) planete4 = CreateSphere ( 32 , pivotplanete4 ) EntityRadius planete4 , 1100 EntityType planete4 , type_ellipsoide ScaleEntity planete4 , 1000 , 1000 , 1000 EntityTexture planete4 , textureplanete4 Collisions type_ellipsoide , type_ellipsoide , 1 , 3 HidePointer ; api_ShowWindow(SystemProperty$("AppHWND"), 1) ; with user32.dll While Not KeyHit ( 1 ) ;pivot ref change If parentplayer0 = 0 Then If EntityDistance ( player0 , pivotplanete4 ) < 3000 Then oldpitch# = EntityPitch# ( player0 , 1 ) oldyaw# = EntityYaw# ( player0 , 1 ) oldroll# = EntityRoll# ( player0 , 1 ) EntityParent player0 , pivotplanete4 , 1 AlignToVector pivotorbiplanete4 , EntityX ( player0 ) , EntityY ( player0 ) , EntityZ ( player0 ) , 2 EntityParent player0 , pivotorbiplanete4 , 1 RotateEntity player0 , oldpitch# , oldyaw# , oldroll# , 1 ;memo local rotations campitch# = EntityPitch# ( player0 , 0 ) camyaw# = EntityYaw# ( player0 , 0 ) camroll# = 0 ; EntityRoll# ( player0 , 0 ) EndIf ElseIf parentplayer0 = pivotorbiplanete4 Then If EntityDistance ( player0 , pivotplanete4 ) > 3200 Then oldpitch# = EntityPitch# ( player0 , 1 ) oldyaw# = EntityYaw# ( player0 , 1 ) oldroll# = EntityRoll# ( player0 , 1 ) EntityParent player0 , 0 , 1 RotateEntity player0 , oldpitch# , oldyaw# , oldroll# , 1 ;memo local rotations campitch# = EntityPitch# ( player0 , 0 ) camyaw# = EntityYaw# ( player0 , 0 ) camroll# = 0 ; EntityRoll# ( player0 , 0 ) ElseIf EntityDistance ( player0 , pivotplanete4 ) < 3100 Then EntityParent player0 , pivotplanete4 , 1 AlignToVector pivotorbiplanete4 , EntityX ( player0 ) , EntityY ( player0 ) , EntityZ ( player0 ) , 2 EntityParent player0 , pivotorbiplanete4 , 1 EndIf EndIf RotateEntity player0 , campitch# , camyaw# , camroll# MoveEntity player0 , mvx , 0 , mvz parentplayer0 = GetParent ( player0 ) Collisions type_ellipsoide , type_ellipsoide , 1 , 3 UpdateWorld RenderWorld If parentplayer0 = 0 Then Text GW/4 , 100 , "Free cosmos" , 1 Else If parentplayer0 = pivotorbiplanete4 Then Text 3*GW/4 , 100 , "Planet orbit" , 1 deplacy# = MouseYSpeed ( ) * mouse_move_speed# deplacx# = MouseXSpeed ( ) * mouse_move_speed# MoveMouse GW / 2 , GH / 2 Flip 0 Delay 1 mvx = 0 mvz = 0 If KeyDown ( 200 ) Or KeyDown ( 17 ) Then mvz = vitesse If KeyDown ( 208 ) Or KeyDown ( 31 ) Then mvz = - vitesse If KeyDown ( 205 ) Or KeyDown ( 32 ) Then mvx = vitesse If KeyDown ( 203 ) Or KeyDown ( 30 ) Then mvx = - vitesse campitch# = ( campitch# + deplacy# ) Mod 360 camyaw# = ( camyaw# - deplacx# ) Mod 360 If campitch# > 90.0 Then campitch# = 90.0 If campitch# < -90.0 Then campitch# = -90.0 Wend End Prym |
