types

Type TBullet
Field x:Int
Field y:Int
endtype

Global Bullet:TBullet

Function playershoot(x:Int,y:Int)

Bullet = New TBullet
Bullet.x = sx
Bullet.y = sy
EndFunction

Function draw()
DrawImage imbullet, bullet.x,bullet.y'now it says it dosnt recognize the variables "x" and "y"
EndFunction

Function update()
Bullet.x = +1
EndFunction 

You delcared it global within a function.

I think dreamora thinks the whole thing is within a type because you didnt put a end type. And if that is the case you only use global stuff within type functions.

And in that case the below should work

Type TBullet
global x:Int
global y:Int




Function playershoot(x:Int,y:Int)
TBullet.x = sx
TBullet.y = sy
EndFunction

Function draw()
DrawImage imbullet, TBullet.x,TBullet.y'now it says it dosnt recognize the variables "x" and "y"
EndFunction

Function update()
TBullet.x = +1
EndFunction 

But I should tell you now it looks like your going down the wrong direction.

You should be looking at list, methods, etc.

Editings:
Heres what i would do...

Type TBullet

	Field x%, y%
	
	Function Create:TBullet(_x%, _y%)
	
		Local b:TBullet = New TBullet
		b.x = _x
		b.y = _y
		Return b
		
	End Function
	
	Method Draw()
	
		DrawRect x, y, 10, 10
		
	End Method
	
	Method Update()
	
		x:+ 10
			
	End Method
	
End Type

Type TPlayer

	Field x%, y%
	Field bulletList:TList
	
	Function Create:TPlayer(_x%, _y%)
	
		Local p:TPlayer = New TPlayer
		p.bulletList = CreateList()
		p.x = _x
		p.y = _y
		Return p
		
	End Function
	
	Method Update()
	
		If MouseDown(1) Then
		
			bulletList.AddLast ( TBullet.Create(x, y) )
			
		EndIf
		
		For Local b:TBullet = EachIn bulletList
		
			b.Update()
			If b.x > GraphicsWidth() + 10 Then 
				bulletList.Remove(b)
				b = Null
			EndIf
			
		Next
		
	End Method
	
	Method Draw()
	
		DrawOval x, y, 20, 20
		
		For Local b:TBullet = EachIn bulletList
		
			b.Draw()
			
		Next
		
	End Method
	
End Type

Graphics 800, 600

Local player:TPlayer = TPlayer.Create(MouseX(), MouseY())

While Not KeyHit(KEY_ESCAPE)

	Cls
	
	player.x = MouseX()
	player.y = MouseY()
	
	player.Update()
	player.Draw()
	
	Flip
	
Wend

End

Tho that dose work I would suggest reading and understanding the tutorials that have been written about the subject of OOP design and BMax OOP.
