    Deciding on an Engine...

    in General Discussion

    Posted

    I have used older versions of Torque. You can get something up and running quickly, especially multiplayer, but than you can hit a pretty solid wall. Bugs can be extremely difficult to troubleshoot. And the forums needed cleaned out at the time. Still, the advantage of having your multiplayer component very accessible is a big win.

     

    As an amateur/hobbyist programmer, I feel LE gives me lot of freedome, and though I hit walls, I steadliy overcome them. It just feels like more things are possible in LE.

    Which language?

    I'll be the guy who endorses Blitzmax then. If you come from a BASIC background, and hate pointers, addressof, and you aren't going pro, then you might want to look at Blitzmax with the BlIDE IDE.

    After days of experimenting, here is the magic order of operations that allowed me to have smoother movement with a "drifting third person camera" without requiring a pivot.

     

     

    'Main loop

    While Not KeyHit(KEY_ESCAPE)

     

     

     

    If KeyHit(KEY_ESCAPE) Exit

    If AppTerminate() Exit

     

     

     

    player.Update() 'captures my keyboard input, applies forces to the fighter.

     

     

    fw.Update()

     

    fw.Render()

     

     

    PositionEntity(fw.Main.camera, EntityPosition(player.model))

    RotateEntity(fw.Main.camera, EntityRotation(player.model))

    MoveEntity(fw.Main.camera, Vec3(0, 1, - 2.5))

     

     

    Flip

     

    Wend

    Remove UpdateFramework() also why this is called on loop?:

    Else 'using pivot
EntityParent(fw.Main.camera, player.camPivot)
PositionEntity(fw.Main.camera, EntityPosition(player.camPivot))

End If

    Parenting a cam to a pivot it's something you should do just once..

     

    I still get the shaky camera. I have minimized my loop to just what causes the shaky camera. I had the other code in there before to demonstrate that using the pivot allowed smooth movement. The following code excerpt, which maneuvers the camera is what creates the jerky results.

     

     

    'SetStats(2)

    EntityParent(fw.Main.camera, Null)

     

     

    'Main loop

    While Not KeyHit(KEY_ESCAPE)

    DebugPhysics KeyDown(KEY_P)

     

    player.Update()

     

    PositionEntity(fw.Main.camera, EntityPosition(player.model))

    RotateEntity(fw.Main.camera, EntityRotation(player.model))

    MoveEntity(fw.Main.camera, Vec3(0, 1, - 2.5))

     

     

    fw.update()

    fw.Render()

     

     

    Flip

     

    Wend

    ..i dont know have you succeeded, and guys previously already did proper explanation, so ill just post some code, how it should look like..so..material file should be as it was already exposed :

    texture0="abstract::cagebulb.dds"
texture2="abstract::cagebulb.dds"
castshadows=0
collisiontype=0
color=1.0,0.9,0.6,1.0
shader="abstract::mesh_diffuse.vert","abstract::mesh_diffuse_glow.frag"

     

    and then, here is example with use if framewerk so it will be very easy to set up and try..

     

    SuperStrict

Framework leadwerks.framewerk
RegisterAbstractPath(AppDir)

Graphics(800, 600)
LogStreamEnabled = False'AppLogMode equivalent
Local fw:TFramewerk

fw = TFramewerk.Create()
If Not fw RuntimeError "Failed to initialize engine."
fw.renderer.SetBloom(True)'here your cagebulb glow will be turned on/off
fw.renderer.setHDR(True)'here your glow effect can be more exposed if HDR is enabled (only SM4 cards)..glow will work just fine without it, but less intense..

'load a scene
LoadMesh("abstract::myScene.gmf")

'just set up your camera to face glowsphere so you can see it
MoveEntity(fw.main.camera,vec3(0,3,-3)

Local glowSphere:TMesh = createsphere() ;moveentity (glowsphere, vec3(0, 3, 0))
Local glowMaterial:TMaterial = LoadMaterial("abstract::cagebulb.mat")
PaintEntity(glowSphere, glowMaterial)


Repeat


 fw.Update()
 fw.Render()

 Flip(0)
Until KeyHit(KEY_ESCAPE)
End

     

    ..and that should be pretty much all...i hope it helps..

     

     

    I can make this example work. Thanks. My problem with Framework now goes back to an earlier post related to camera movement.

    Moving the camera is code creates very jerky movement unless I use a pivot.

     

    I made a brief video showing the problem here: Jerky Camera Using Framework

     

    I only get this using framework.

     

    My relevant code is as follows:

     

    Framework leadwerks.engine

     

    'Create an OpenGL graphics window

     

    Import "Framework.bmx"

     

     

    AppTitle = "Working Title"

     

    Const WIDTH = 1024

    Const HEIGHT = 768

    Graphics WIDTH, HEIGHT

     

    Const FPSVIEW = 1

    Const CHASEVIEW = 2

    Global ViewType:Int = CHASEVIEW

     

    'Allows the engine to find files and load files from zip packages

    RegisterAbstractPath AppDir

     

    fw:TFramework = TFramework.Create()

     

    If Not fw

    RuntimeError "Failed to initialize engine"

    End If

     

    PositionEntity fw.Main.camera, Vec3(0, 10, - 4)

    CameraClearColor(fw.Main.camera, Vec4(0, 0, 0, 1))

    CameraRange(fw.Main.camera, 0.1, 3000)

    CameraClearMode(fw.Main.camera, BUFFER_DEPTH)

     

    'add a light

    light:TLight = CreateDirectionalLight()

    RotateEntity light, Vec3(45, 45, 0)

     

    'load the scene

    scene:TEntity = LoadScene("abstract::scene.sbx")

    If Not scene RuntimeError "Failed to load scene"

     

     

     

    'set collisions

    Collisions(1, 1, True)

     

     

    Global player:TTIEF

    player = New TTIEF

    player.SetPosition (0, 50, - 2000)

     

     

    LoadTestTower()

     

    SetSkybox(LoadMaterial("abstract::skybox.mat"))

     

    HideMouse

    MoveMouse GraphicsWidth() / 2, GraphicsHeight() / 2

     

     

    'SetStats(2)

     

    'Main loop

    While Not KeyHit(KEY_ESCAPE)

    DebugPhysics KeyDown(KEY_P)

     

     

    If KeyDown(KEY_S) Then SaveBuffer(gbuffer, "screenshot.jpg")

     

    If KeyDown(KEY_F1) Then ViewType = FPSVIEW

    If KeyDown(KEY_F2) Then ViewType = CHASEVIEW

     

    UpdateFramework()

     

    player.Update()

     

    'Position Camera

    If ViewType = CHASEVIEW 'no pivot

    EntityParent(fw.Main.camera, Null)

    PositionEntity(fw.Main.camera, EntityPosition(player.model))

    RotateEntity(fw.Main.camera, EntityRotation(player.model))

    MoveEntity(fw.Main.camera, Vec3(0, 5, - 10))

    Else 'using pivot

    EntityParent(fw.Main.camera, player.camPivot)

    PositionEntity(fw.Main.camera, EntityPosition(player.camPivot))

     

    End If

     

     

     

     

     

     

    fw.update()

    fw.Render()

     

    If ViewType = FPSVIEW Then

    DrawText "View Type: Using Pivot", 0, 80

    Else

    DrawText "View Type: Rotating Cam", 0, 80

    End If

     

     

    Flip

     

    Wend

     

     

    I have also played around with resizing the model in case its a rounding error with floats, but that didn't seem to help. Not moving the camera keeps everything smooth as well.

     

    Any thoughts?

    Could you show us the whole code so we can try to help you?

     

     

    Thanks for your time.

    CameraClearColor(cam, Vec4(0, 0, 0, 1))

    RotateEntity(cam, Vec3(35, 0, 0))

    MoveEntity cam, Vec3(0, 2, - 2)

    SetShadowSoftness(plight, 2)

    SetShadowmapSize(plight, 512)

    SetLightRange(plight, 2)

     

    plight_material:TMaterial = CreateMaterial()

    SetMaterialTexture(plight_material, LoadTexture("abstract::cagebulb.dds"))

    PaintEntity(plight, plight_material)

    AmbientLight Vec3(1)

     

    PositionEntity model, Vec3(0, 2, 0)

     

    'Main loop

    While Not KeyHit(KEY_ESCAPE)

     

    TurnEntity model, Vec3(0, 0.5, 0)

     

    'Update timing, physics, and other miscellaneous updates

    UpdateWorld

     

    'Draw the world

    SetBuffer(buffer)

    RenderWorld

    'Swap the graphics buffers so we can see what we drew

     

    SetBuffer(BackBuffer())

    RenderLights(buffer)

    Flip

    Wend

     

    The screenshot shows what I'm getting. Not quite the bright light of the tunnel demo.

     

    Thanks again.

    Its funny. Using Framework, the camera's movements are jerky and it makes my ship look like it is vibrating violently. When I don't use framework, its fine, but getting the advanced effects are ten times harder.

     

    In your example, you use a cube. Have you used a model with it yet? I am wondering if the physics body is messing me up.

     

    When I comment out the camera positioning, the TIE moves fine as does when I use the pivot.

     

     

    I am still stuck trying to reproduce a simple use of the GLOW shader working such as the cagelight in the tunnels example. Any BMAXers out there have a working example of something like this?

    Actually the thread you are referencing is all about the problems that arose from that approach. In the end I went for this approach for a basic third person camera:

    And then to this:

    I am not sure what category this question comes under but is it possible to have an animated character run across a scene and knock over an object such as a oildrum or crate etc?

     

    You should be able to fine. You may need to play with values like mass. Use setbodymass fcor example.
