quick question am i placing the function in the right place it not working right. sorry for sounding like a pain asking a lot of question

Graphics3D 800,600,2

Global max_life = 6
Global heart_container = 1
Global rupy = 0
Global key = 0
Global bomb = 0
Global red_rupy = 1
Global blue_rupy = 5

Const cube_col = 1
Const sphere_col = 1

SetBuffer BackBuffer()

camera=CreateCamera()
CameraViewport camera,0,0,800,600
PositionEntity camera,0,0,-5

light= CreateLight()

cube=CreateCube()
PositionEntity cube,-5,0,5
EntityColor cube,70,80,190
EntityType cube,cube_col

sphere=CreateSphere(12)
PositionEntity sphere,5,0,5
EntityColor sphere,170,80,90
EntityType sphere,sphere_col

Collisions sphere_col,cube_col,3,1

While Not KeyDown(1)

gui()

If KeyDown(200) Then
MoveEntity sphere,0,.1,0
EndIf
If KeyDown(208) Then
MoveEntity sphere,0,-.1,0
EndIf

If KeyDown(205) Then
MoveEntity sphere,.1,0,0
EndIf
If KeyDown(203) Then
MoveEntity sphere,-.1,0,0
EndIf

Function gui()
Text 540,10, "- LIFE -"

If max_life = 0

End Function

End

Its sort of in the right place, but you're calling it twice in your main loop.

Also, three of the six text commands (rupy, key, bomb) have the wrong syntax - there should either be something before the +, or the + shouldn't be there at all.

i can put empty quotations in front of them "" also the qui() that doesn't have the function should be before the update world then.

You seem to have forgotten 'End If'

If max_life = 0 
   Text 350,290," Game Over!"
End If

i notes there an other problem now

the new function i put in is also giving me problems as well. i'm trying to get it so that if i collide to the cube that it losses 1 life point

"Sphere" isn't visible within "death_cube", as it's a local in the main program's scope. You need to either declare it as a global, making it visible everywhere (bad), or add a parameter to "death_cube" which you use to pass the value in, and use that parameter to refer to the sphere in question.

e.g.

...
death_cube(sphere)
...

Function death_cube(sp)
If EntityCollided(sp, cube_col) Then
max_life = max_life -1
End If
End Function
