| Hello, I was wondering how you would go about making some like say.. a door. If you click on the door it does something. I'am not sure how to make it clickable. Any help would be much appreciated. |

| The Blitz3D Beginners Area forum is more appropriate for this kind of questions. You want to use a combination of EntityPickMode() and CameraPick() or LinePick(). EntityPickMode() is used to make a mesh "pickable". CameraPick or LinePick is used to throw a ray from a point and then you can retrieve the picked "pickable" pointer, and infos about the pick (x,y,z,nx,ny,nz) Preferably, you want to use a low tris mesh for each "pickable", or EntityRadius or EntityBox. |

| I've messed with those, but I'm having trouble trying to actually tie it to a keypress. |

You could try something like this(pseudo code):
If KeyDown(28)=True and distance_to_object<door_range or collided_with_doorobject=true then
MoveEntity Door, Xunits, 0,0
Endif
Where of course the enter key is being used to open the sliding door. |

This has got me stumped. Blitz3d is the first language I've actually sit down and actually put effort into learning. So bare with me if I don't quite understand something. Thanks for the help I am getting. I really appreciate it.Function Jail() ; Starting zone
Cls
started = True ;Room
PlayerData()
FreeImage (start_btn)
Cls
PlaySound(Jailsound)
Jail = LoadMesh("Media\Meshes\Jail\Jail.b3d")
PositionEntity(Jail,0,0,0)
ScaleEntity(Jail,1.2,1.2,1.2)
EntityType Jail, Type_Jail
box = CreateCube() ; Clickable Test subject
EntityPickMode box,2
x = 0
z = 5
PositionEntity box,x,0,z
ScaleEntity box,20,20,20
If MouseHit(2) Then CameraPick(cam,MouseX(),MouseZ())
End Function |
