Hi Ats, I'm trying to retrieve the screen resolution inside a shader What do you need the screen resolution for in your shader? If it's just to calculate "ditherScale", then simply calculate that value in a ZExpression instead and pass the result as a ShaderVariable. But it's easier to giv...

Hmm, @Ville: Maybe instead of just translating the preview ( of MeshEditFrame ) based on Mesh.BoundSphere, the (model)view matrix could also be scaled ( using BoundSphere.Radius ) so that the mesh fits in view by default? That way you don't have to fiddle with the clipping range / projection matrix. K

Hi, I run a program on Windows using DLL, but when I compile it to Android, it doesn't run on Android, what should I do? A DLL file is very similar to a EXE file and is therefore platform-specific and will only work on Windows. Android has a similar shared library concept though, using the SO extens...

Hi zakkwylde, Sorry to bring up such an old post but i realized that the shot models in your FPS engine does not follow the crosshairs at extreme angles (i.e. vertically up and down). Would you know the fix for these? In order to fix jph's "basic_FP_engine_001.zgeproj" project, change the ...

Hi jinxtengu, Below is a simple example ( containing 8 white boxes and a animated camera ) that enables blue exponential fog with a density of 0.05: <?xml version="1.0" encoding="iso-8859-1" ?> <ZApplication Name="App" Caption="ZGameEditor application" FileVer...

Hi Ats, Contrary to the zbtCreateTriangleMeshShape function, I don't get the points array. Should they be stored in a certain order? Nope .. the points don't have to be in a certain order. As quoted from the Panda3D documentation: A good analogy for a convex hull is an elastic membrane or balloon un...

Hi Ats, Just to be sure, what float* triangles array would look in ZGE for a single triangle, something like this? Yup .. the btTriangleMesh(false, false) call gives you a mesh with 3-components ( XYZ ) per vertex using 16-bit indices ( so no more than 65536 vertices total ). Then the addTriangle ca...

Hi Ats, There is a fourth value that can be set for CollisionBounds, besides X,Y and Z. So what is it? It's ( currently ) not used by any of the collision styles. How to set/get it by code? Both XYZW and RGBA can be used with any 4D vector. So in order to access the 4th component of CollisionBounds ...

Hi Ats, I guess it is some kind of limitation with int or float size, but I don't understand why...? A signed 32-bit integer has a range of -2147483648 to 2147483647. Which means you can safely multiply the fractional part of a float by ( up to ) 10⁸ .. so that's all fine. However, a 32-bit float us...

Hi Ats, I'm trying with a SkyCylinder, that only rotates on its X axis. It should work, but the cylinder mesh ZGE Library.xml is made out of a sphere, without texture coordinates. For your purpose you want to generate a cylinder from a 2D-grid. The normals aren't necessary ( for sky-cylinder use ) ....

Hi Ats, So I'm planning to replace the background rectangle by a skybox. But I don't know how to get rid of the visible edges and corners of the cube. Is this possible, or should I use a skysphere instead? If you want to use a skybox .. you need a texture that has been projected onto a box. Similarl...

Hi Ats, I can simply retrieve the offset in my sketchup ruby script and store it with the rest, it will be easier and ready for release too. That's definetely more convenient than having to do it in ZGE. The sketchup and ZGE axis don't have the same rotation Right, there's no consensus .. software l...

Hi Ats, With this new method, it is simpler to export models to ZGE without having to center them, so that, as an example, the pyramid can be put on the ground by setting its Position.Z = 0, instead of Position.Z = -pyramidHeight/2. Right, it's important to place your mesh origin correctly so that y...

Hi Ats, Are you you putting the transformation ( position / rotation / scale ) values in the SketchUp object names or something? Or are those simply the variable names your script generates from the object values? Anyway, for a compound shape i'd use a parent object / dummy that ( for instance ) has...

Hi Ats, And I rediscover why I completely stopped working on Omeganaut: setting the collision shapes is a hassle. This all comes down to preference, but for imported meshes i'd personally define the collision shape(s) in the software you're using to create them ( Blender / Maya / ??? ) and use a cus...
