Irrlicht Lime is a .NET wrapper for Irrlicht Engine

Okay. Thank you.

TextBoxs on second windows.form?

I have Irrlicht Lime running in it's default form or one I created. Then Iv got a from that opens on the side of the render form.
The TextBoxs I put on the other form don't work properly. (can't type anything) unless I show the form with .ShowDialog
The TextBoxs are getting focus and are getting KeyDown & KeyUp but no KeyPress.

Anybody got any ideas so I don't have to have it as a dialog?

[greenya]

Well, need to test that and say my diagnosis. But that is very likely, since Irrlicht dispatches the events in its own way. For now i can say for sure that for example if you have Irrlicht rendering window inside your form (i mean you create Irrlicht device providing window handle) your FPS camera will not be able to receive mouse events, and this is the same behavior for native Irrlicht + Win32 usage too.

if you have Irrlicht rendering window inside your form (i mean you create Irrlicht device providing window handle) your FPS camera will not be able to receive mouse events, and this is the same behavior for native Irrlicht + Win32 usage too.

Using:

Code: Select all

Dim frmRender As new Form
sub main()
        frmRender.Show()
        Dim deviceParamerters As New IrrlichtCreationParameters
        deviceParamerters.DriverType = DriverType.Direct3D9
        deviceParamerters.WindowID = frmRender.Handle
        Device = IrrlichtDevice.CreateDevice(deviceParamerters)
 

I still get mouse & keyboard events through Irrlicht Lime.

I was able to get it working using:

Code: Select all

Dim t As New Threading.Thread(Sub()
                             Application.Run(New ApplicationContext(New Form))
                             End Sub)
t.SetApartmentState(Threading.ApartmentState.STA)
t.Start()
vs
Dim frm As Form
frm.Show()

Witch likely isn't the best way to do it. But it seems to work.

i see that you have also a nuget package.
Why it's not updated?

[greenya]

Well, i haven't made any nuget packages, and didn't know about its existence for Irrlicht Lime until you said. I will try to contact the author and ask to update it.

When I do this code,

Code: Select all

Dim node = scenepanel.device.SceneManager.AddLightSceneNode(Nothing, New IrrlichtLime.Core.Vector3Df(-5, 5, 10))
        scenepanel.ChangeSelected(node)
        Dim billboard As IrrlichtLime.Scene.BillboardSceneNode = scenepanel.device.SceneManager.AddBillboardSceneNode(node)
        Dim light_text As Video.Texture
        Try
            If My.Computer.FileSystem.FileExists("textures/editor_defaults/grass1.jpg") = False Then
                log.print("Texture File does not exist: textures/editor_defaults/default_light.jpg")
                Exit Try
            End If
 
            light_text = scenepanel.device.VideoDriver.GetTexture("textures/editor_defaults/grass1.jpg")      <--- error here
            billboard.SetMaterialTexture(0, light_text)
        Catch ex As Exception
 
        End Try
        
        billboard.SetMaterialType(Video.MaterialType.TransparentAddColor)
        billboard.SetMaterialFlag(Video.MaterialFlag.Lighting, False)

Hello.
I don't see any problem with the code. If texture file doesn't exist GetTexture will simply return null (Empty in terms of VB if i'm correct).
Please provide "grass1.jpg", maybe it is a key to crashing app.
Do you have this problem with any texture or only with particular like "grass1.jpg"?
Also maybe some problems with access rights to file in your OS, not sure about that.

I also tried loading .png and other .jpg files, but they do not work.

I tried giving the GetTexture function a IO::ReadFile variable, but it fails to execute on a similar overload function

It seems that the data has been corrupted else where, I posted a link to the complete source above.

[greenya]

I could not reproduce the problem. I checked in C# and VB, I checked with path that contains Unicode characters (Cyrillic and Chinese) and all worked OK. It seems that problem is somewhere else.

Please confirm next:
1) all the examples that comes with Lime works fine for you.
2) you did not replaced original Irrlicht.dll that comes with Lime SDK with one that you may downloaded from Irrlicht Engine official SDK.

[rubenwardy]

I can not open any of the examples. They do not appear to be written in Visual Basic

[greenya]

When you download Irrlicht Lime archive, it contains bin/Release folder where placed all the examples which are already compiled. They all can be started simply by double clicking on any of them and should run OK. Please confirm that they runs OK on your system.

[greenya]

Version 1.3 has been released

New examples:

L14.Pathfinding // shows pathfinding on 64x48 map using simplified A* algorithm. // preview
L15.AbstractTrace // generating abstract traces using plane of rarely set cubes. // preview

Changes:
- Updated Irrlicht SDK to trunk rev. 4446.
- MaterialRendererServices changes: added GetPixelShaderConstantID and GetVertexShaderConstantID. Updated methods to take index instead of name. Renamed SetPixelShaderConstant (and "Vertex") which took argument "startRegisterIndex" to SetPixelShaderConstantList (and "Vertex"). Removed SetPixelShaderConstant (and "Vertex") with "bool" argument.
- GUIEditBox changes: added get-set props CursorBlinkTime, CursorChar, DrawBackground and DrawBorder. Removed SetDrawBorder method.
- Added DrawBackground and DrawBorder props to GUICheckBox.
- Added ValidateOn prop to GUISpinBox. Added GUISpinBoxValidation enum.
- Added AddShadowVolumeSceneNode to MeshSceneNode.
- Added BoundingBoxTransformedEdges to SceneNode.
- Added ButtonPressedImageOffsetX, ButtonPressedImageOffsetY, ButtonPressedTextOffsetX and ButtonPressedTextOffsetY to GUIDefaultSize enum.
- Added Disabled to ComparisonFunc enum.

[rubenwardy]

I attempted to run the examples, and they work.

[greenya]

Well, then i can't say why your code cannot open texture
