Framework and BMX question or two

[Madjack]

So I've finally gotten my ex-Xors + BMX codebase to compile under Leadwerks.

 

From what I can tell, the way to go is to use Framework in order to have easy access to LE's various special fx. Is that correct? Any issues I should be aware of with Frameworks + BMX?

 

I've grabbed the copy from the SDK install and incorporated it into my code.

 

An initial problem is that some commands mentioned in the docs + wiki don't seem to be included in the BlitzMax version. Namely:

 

GetFrameworkLayer

GetFrameworkListener

GetLayerCamera

GetLayerWorld

 

What am I missing?

 

<edit> or could I write my own functions for the above? Something like;

 

Local LAYER_DEFAULT:TLayer = GetFrameworkLayer(1)
Local CAMERA:TCamera = GetFrameworkCamera(LAYER_DEFAULT)

Function GetFrameworkLayer:TLayer(LAYER_index:int)
select LAYER_index
 case -1; Return fw.background
 case 0; Return fw.Main
 case 1; Return fw.transparency
end select
End Function


Function GetFrameworkCamera:TCamera(LAYER_check:TLayer)
 Return LAYER_check.CAMERA
End Function

Setup your application directory, make sure you have a copy of the scripts directory in the SDK copied to it along with newton.dll and shaders.pak. You will also need to set up lua-gluefunctions.bmx in the same directory. This can be created by running:

 

SuperStrict

Framework leadwerks.engine

Import "PATH TO YOUR 2.x SDK FOLDERBMXFrameworkframework.bmx"

Import lugi.generator

generateGlueCode("lua-gluefunctions.bmx")

Notify "lua-gluefunctions.bmx Generation Complete"

End

 

 

Then use the following for a simple framework context:

 

 

SuperStrict

Framework leadwerks.ENGINE

Import "PATH TO YOUR 2.x SDK FOLDERBMXFrameworkframework.bmx"

Include "lua-gluefunctions.bmx"


AppTitle:String = "Blank"

GCSetMode(2)

RegisterAbstractPath "PATH TO YOUR 2.x SDK FOLDER"

Graphics(800,600)


AFilter(4)
TFilter(1)

Global fw:TFramework = TFramework.Create()
If Not fw RuntimeError "Failed to initialize engine."

SetScriptObject("fw", fw)

SetBackgroundColor(Vec4(0.0,0.0,0.5,1.0))

SetZoom(1.25)

SetStats(2)

PositionEntity(fw.Main.camera,Vec3(0.0,0.0,0.0))

Repeat
If KeyHit(KEY_ESCAPE) Exit
If AppTerminate() Exit

 UpdateFramework()
 RenderFramework()

Flip()

Forever
fw.renderer.gbuffer = Null
GCCollect()
End

Function StringToVec2:TVec2(text:String, scale:Float = 1.0)
	Local t:TVec2 = Vec2(1)
	Local sarr:String[]
	sarr = text.split(",")
	If sarr
			If sarr.length > 0 t.x = Float(sarr[0]) * scale
			If sarr.length > 1 t.y = Float(sarr[1]) * scale
	EndIf
	Return t
EndFunction

Function StringToVec3:TVec3(text:String, scale:Float = 1.0)
	Local t:TVec3 = Vec3(1)
	Local sarr:String[]
	sarr = text.split(",")
	If sarr
			If sarr.length > 0 t.x = Float(sarr[0]) * scale
			If sarr.length > 1 t.y = Float(sarr[1]) * scale
			If sarr.length > 2 t.z = Float(sarr[2]) * scale
	EndIf
	Return t
EndFunction

Function StringToVec4:TVec4(text:String, scale:Float = 1.0)
	Local t:TVec4 = Vec4(1)
	Local sarr:String[]
	sarr = text.split(",")
	If sarr
			If sarr.length > 0 t.x = Float(sarr[0]) * scale
			If sarr.length > 1 t.y = Float(sarr[1]) * scale
			If sarr.length > 2 t.z = Float(sarr[2]) * scale
			If sarr.length > 3 t.w = Float(sarr[3]) * scale
	EndIf
	Return t
EndFunction

	Local size:Int=GetStackSize()
	lua_pushbmaxobject(luastate.L,o)
	lua_setglobal(luastate.L,name)
	SetStackSize(size)
EndFunction

Function GetStackSize:Int()
	Return lua_gettop(luastate.L)
EndFunction

Function SetStackSize(size:Int)
	Local currentsize:Int=GetStackSize()
	If size<currentsize
	lua_pop(luastate.L,currentsize-size)
	EndIf
EndFunction

Thanks for that - I've followed the steps listed and framework appears to be up and running.

 

Next step, get my background/distant terrain rendering up and running again.
