| The "Game" is over, now it is a project and i call it "S3D". Today it is just a really small update: added : ScaleEntity:Void(entity:Entity, x:Float = 1.0, y:Float = 1.0, z:Float = 1.0) changed : Entities do not more ignore his scale factor changed : cleanup source changed : source splitted http://www.sedm.de/monkey/s3d/s3d.zip the next big thing are real cameras. the whole scene must be transformed if you move or rotate the camera. Then the "ObjLoader" Class has to be extended for more flexibility, more then one texture layer und for so many things that i think this thing will never be ready :) Animations are a big theme, i've atm no idea about animations with vertex buffer objects ... but i think thats just a hole to jump over that. once again: excuse me for my bad english ;) |
| ||
| Nice! will give this one a go when i have time. |

v0.12 is online ... here's the changelog:added : Vector.setW:Void(w:Float = 1.0) added : Light.setLightType:Void(lightType:Int = 1.0) added : Entity.addChild:Void(child:Entity) added : Mesh.setCulling:Void(culling:Int = 0) added : MeshCulling:Void(mesh:Entity, culling:Int = GL_BACK) changed : S3D.createCamera() now has the optional parameter "parent:Entity" changed : S3D.createLight() now has the optional parameter "lightType:Int = LIGHT_POINT" and "parent:Entity" changed : S3D.loadMesh() now has the optional parameter "parent:Entity" changed : S3D.refMesh() now has the optional parameter "parent:Entity" changed : CreateCamera() now has the optional parameter "parent:Entity" changed : CreateLight() now has the optional parameter "lightType:Int = LIGHT_POINT" and "parent:Entity" changed : LoadMesh() now has the optional parameter "parent:Entity" changed : CloseMesh() now has the optional parameter "parent:Entity" changed : you can now use transparent texures changed : backface culling is now active per default but set to "no culling" surprise: the Example works on Android, GLFW and iOS  Now the archive contains a folder "modules" and a folder "bananas" so you can extract the full S3D update over your monkey installation. The example in bananas/s3dExample shows a small island in the sky with a tree and a rock. If you want to compile this you have to build the example (not run), go to the build folder and open the CONFIG.TXT. Add "|*.obj|*.mtl" to the list of textfiles and rebuild the example. I've test it with all available opengl.gles11 targets and it will work. Important: Ever use "SetUpdateRate" in OnCreate() ;) http://www.sedm.de/monkey/s3d/s3d.zip have fun! |
| ||
| Nice, and it runs very smoothly on my Android phone. The B3D-style command set is also very welcome! |
| ||
| Can't wait to try this! Though when you said ever use "SetUpdateRate" in OnCreate(), did you mean "never"? And if so, could you please explain why? :O |
| ||
| i get this error with glfw (ClCompile target) -> c:\dropbox\monkey\bananas\s3dexample\example.build\glfw\main.cpp(4975): error C2661: '_glNormalPointer' : no overloaded function takes 3 arguments |
| ||
| I guess it doesn't work with a macbook pro 5,5 with nvidia graphics. TRANS FAILED: TRANS Failed to execute 'xcodebuild -configuration Debug', return code=16640 |
| ||
| @Hima: with "ever" i mean "ever". I've forgot it sometimes and spend hours in debugging ;) @slenkar: this is a bug in the gles11 module. You must override the normalpointer function with a version with 3 parameters: open /modules/opengl/native/gles11.glfw.cpp and search for this function:
void _glNormalPointer( int size,int type,int stride,int offset ){
glNormalPointer( type,stride,(const void*)offset );
}
create a copy of this function and remove the parameter "size":
void _glNormalPointer(int type,int stride,int offset ){
glNormalPointer( type,stride,(const void*)offset );
}

| ok it builds now thanks, this is how my config.txt file looks like TEXT_FILES=*.txt|*.xml|*.json|*.obj|*.mtl but the game still cant load the isle.obj file |
| ||
| please check the IMAGE_FILE config, should look like this: IMAGE_FILES=*.png|*.jpg I've uploaded a GLFW binary, can you check whether it will run? http://www.sedm.de/monkey/s3d/s3dglfw.zip |
| ||
| the binary doesnt run dont know why |
| ||
| please tell me your system specs |
| ||
| I receive an error about system32/ct_oal.dll Then the binary works and I see the island. |
| ||
| @Volker: have you Monkey 052b installed? [EDIT] wait, you have to install OpenAL > http://connect.creativelabs.com/openal/Downloads/oalinst.zip [/EDIT] |

| GLES1.1 based on OpenGL1.5 ... that means: you can not run Monkey GL code on your machine. |
| ||
| This would, of course, belong in another thread in another forum, but would it be possible to get a walk through of how the models were created/textured/exported for use in Monkey? I'm not a 3D guy, but would like to learn more, and some kind of starter tutorial somewhere would be awesome. |
| ||
I thought you can use a new logo after renaming your project so I through something together: |
| ||
| GLES1.1 based on OpenGL1.5 ... that means: you can not run Monkey GL code on your machine. Me and old betsy are gonna have to go for a walk with a shotgun BOOM! (in other words I will purchase a new PC) |
| ||
| @Shinkiro1 : thanks for your participation, but as you see ... i've already create a new logo ;) @slenkar: maybe a driver update will help or just a new graphics card? But you should keep in mind: Your computer is a dinosaur! @project v013 takes a while, the camera control is very difficult because i must transform the whole scene. Stay tuned. |
| ||
| if anybody want ask for ES2.0 ... still wait for S3DX, it is'nt possible to create a 2.0 module with a fallback to 1.1 .. so i must create two modules. |
| ||
| i've splitted the project in three branches: s3d.S3D11 for OpenGL ES1.1 s3d.S3D20 for OpenGL ES2.0 s3d.S3DDX for a DirectX based version for XNA (very experimental) a new version will come in the next few days. |
| ||
| Very interesting, Android + iOS + XNA support sounds great! |
| ||
| On both, GLFW and IOS I get depth buffer sorting problems. What could be the reason? |
| ||
| you have to set DEPTH_BUFFER_ENABLED in the CONFIG.TXT. Look at your build folder. |
| ||
| Thanks that did the trick. Still some alpha errors are visible but it is promising. Thanks for the effort you put into this. |
| ||
| Hmmmm, I tried running the example with an OBJ exported by Google SketchUp Pro and it dies because the object fails to load. OBJ file: http://cheesekeg.com/archlinux.zip example.monkey: Import mojo
Import s3d.s3d
Class App3D Extends App
Field isle:Mesh', cam:Camera, l:Light
Method OnCreate()
Local cam:= CreateCamera
Local l:= CreateLight
isle = LoadMesh("archlinux.obj")
MeshCulling(isle, GL_BACK)
PositionEntity isle, .0, -.7, -2.0
CameraClsColor cam, 0, 128, 255
SetUpdateRate 60
End
Method OnUpdate()
TurnEntity isle, 0.0, 1.0, 0.0
End
Method OnRender()
RenderWorld
End
End
Function Main()
New App3D
End
Output: Build succeeded.

I like where this is going; rapid prototyping FTW! Do you plan on continuing this project/hosting a repository for it? I'd love to play with it! |
| ||
| Had no time to check this out in detail, but are you sure you have "*.obj" in CONFIG.TXT file in the build folder? Make sure the .obj file actually is in the .build/[target name]/data folder. |
| ||
| you can also rename your *.obj to *.txt and yes ... this project will be continued, but at this time i've not enough time. to many projects ;-) |
| ||
| Thanks for the responses. Running the example with the provided "isle.obj" works fine for me, but running it with my "archlinux.obj" results in the failure stated above. My apologies for not clarifying this in my previous message! Here are the GLWF/Android configurations respectively: GLFW - CONFIG.TXT GLFW_WINDOW_TITLE="Monkey Game" GLFW_WINDOW_WIDTH=640 GLFW_WINDOW_HEIGHT=480 GLFW_WINDOW_RESIZABLE=false GLFW_WINDOW_FULLSCREEN=false CPP_INCREMENTAL_GC=1 OPENGL_GLES20_ENABLED=false OPENGL_DEPTH_BUFFER_ENABLED=false MOJO_IMAGE_FILTERING_ENABLED=true TEXT_FILES=*.txt|*.xml|*.json|*.obj|*.mtl IMAGE_FILES=*.png|*.jpg SOUND_FILES=*.wav MUSIC_FILES=*.wav Android - CONFIG.TXT MOJO_HICOLOR_TEXTURES=true MOJO_IMAGE_FILTERING_ENABLED=true ANDROID_APP_LABEL="Monkey Game" ANDROID_APP_PACKAGE=com.monkey ANDROID_SCREEN_ORIENTATION=portrait OPENGL_GLES20_ENABLED=false ANDROID_NATIVE_GL_ENABLED=false TEXT_FILES=*.txt|*.xml|*.json|*.obj|*.mtl IMAGE_FILES=*.png|*.jpg|*.gif|*.bmp SOUND_FILES=*.wav|*.ogg|*.mp3|*.m4a MUSIC_FILES=*.wav|*.ogg|*.mp3|*.m4a Here's what archlinux.obj + .mtl is supposed to look like:  Does anyone else have a problem running the example using the OBJ I supplied? I also tried the lovely teapot just now and it failed with the same error and stack trace: http://groups.csail.mit.edu/graphics/classes/6.837/F03/models/ Thanks in advance! - Brandon |

| I've no idea what's going wrong in SketchUp, but in Blender i've to check the Exportoptions "Export Normals" and "Triangulate Faces" to create a compatible object file. The S3D Wavefront Importer is very raw and far away from a stable release. |
| ||
| Took a quick look. The problem appears to be that the obj loader doesn't know how to handle quad faces, only triangle ones. Shouldn't be that difficult to add. |
| ||
| all Quads must be converted to Triangles ... if the Exporter doesnt support that, you have to change the Software ... use Blender instead ;) |
