Specifically I need to get the 'dy' member of the NativeFont struct. I tried adding this to the 'FONT' class... Code: private Var dy_ = null; public Var dy { get { unsafe { if (dy_ == null) { dy_ = (Var)(IntPtr)(&((*FONTPointer).dy)); } } return dy_; } } ...yet I'm always getting 0, where as testing in lite-c gives me the value of 20.

This snippet should work. Code: /// <summary> /// dy - see Gamestudio manual /// </summary> public int dy { get { unsafe { return (*FONTPointer).dy; } } } Maybe I will include some unlisted properties of engine objects in the next release (which I will release, when the new engine version isn't in public beta anymore)

Could you please add a definition for it? Edit>>> While we're on the subject of material, I think there may be a bug floating about somewhere. I'm trying to apply the shader 'envglass.fx' from the 'GStudio7\Code' folder to a model... Code: MATERIAL mat_ent = EngFun.mtl_create(); ENTITY entity = EngFun.ent_create("blob.mdl", new Vector(150, 0, 0), null); mat_ent.skin1 = EngFun.bmap_create("t_day_sky+6.tga"); entity.material = mat_ent; entity.SHOW = true; EngFun.bmap_to_cubemap(mat_ent.skin1); EngFun.effect_load(mat_ent, "envglass.fx"); The shader also needs 'default.fx' from 'GStudio7\Include'. The same code works fine in lite-c. I think it may have something to do with the 'mat_ent.skin1' as the shader uses this skin, and modifying the shader to use a skin embedded with the .mdl, works fine.

Thus I will implement a class 'MATRIX' (just like 'ENTITY' or 'VIEW), that offers function to get it's matrix as float[][] or set it with a float[][] and functions or properties to access each part of the matrix, like matrix41... It's necessary to implement the matrix itself as class, as the engine functions can only access unmanaged memory, and thus the class will wrap a float[][] matrix in the unmanaged space of the application. Concerning the bug - I tried your example and found only one difference between the wrapper and the lite-c version (i used the "sf_woman.mdl" as model and "skycube+6.tga" as bmap, both from the template folder) - the lite-c version gave me warnings, that "SKIN#01 - normal or height map missing" and that one 3 times! As I'm a real newbie in shader programming, this doesn't have to mean anything What was the error that occurred in your application ? What did differ between the lite-c and the c# version ? I will fix the wrapper on the weekend - as I don't have that much time during this week ^^ Thanks in advance for your help in spotting down that error! get the C# wrapper: for A7.85.4 and A8.30.4, Version 2.3.9 at http://acknexwrapper2.matthias-auer.net/ or visit the thread

I broke the code down in lite-c, and by not setting material.skin1 to the sky-cube map, then the shader appears like it does in C#, thus I can only assume that material.skin1 is'nt being assigned correctly or something. That 'SKIN#01' error is caused because that particular shader uses additional skins. You can use 'box.mdl' from 'GStudio7\Projects\shadertest' which has all the skins attached as required. Here is a demo in lite-c... http://djbm.kawanda.net/Public/ShaderTest.zip

I've uploaded the project (with a compiled version in the Debug folder) http://www.matthias-auer.net/acknexwrapper/WrapperTestApp.zip hmmmm, I wasn't able to see any difference between the lite-c and the c# version get the C# wrapper: for A7.85.4 and A8.30.4, Version 2.3.9 at http://acknexwrapper2.matthias-auer.net/ or visit the thread

I haven't worked on the shader part in a long time so I guess I just forgot to update it. It's working fine now. Thanks for once again bailing me out of trouble, lol.
