Irrlicht Engine

I understand it...so, if I don't want to write a thousands lines of code, I have to use an external engine to manage collisions more accurately...the problem is that all these engines I know are based on Dynamics and not on Kinematics...

I call as "Collision System" the part of Irrlicht code that manages and detects collisions (maybe I'm wrong and/or I don't know well how Irrlich works for collisions...I'm sorry...) My problem is explained better by these two image: http://img92.imageshack.us/img92/3615/robot2ar2.png http:...

I tested SVN 1829, 1.5 branch, and I have to notice a bug in collision detection system. Even if models' bounding boxes now update correctly during joints' animation (thanks to Rogerborg's good work), collision system works as if they aren't updated yet...so model always stops at the same position a...

I tested the 1.5 branch (downloaded here: http://irrlicht.svn.sourceforge.net/viewvc/irrlicht/branches/releases/1.5/ and compiling it by Visual Studio 2005) and I'm happy to say that mesh buffers' bounding boxes (and consequently total model's bounding box) resize correctly during movement by animat...

Thanks for your interest, I'm waiting the release of new SVN, to test it...I hope that it will solve my problem and I'll report the result!

I use a MilkShape mesh (.ms3d file) without built-in animations. You can download it here: http://www.zshare.net/download/518260856495588a/ I move it using skeletal animation (animating bones), following the section "Joint control" in this wiki: http://www.irrlicht3d.org/wiki/index.php?n=M...

I committed an attempted fix for this last night in SVN 1805, so test reports from the trunk would be very welcome. I tested SVN 1817 (I found that trunk...). I noticed that bones can't move (I used the same code as before, so I cannot test collisions and BBs resizing...), some anomalous positionin...

IAnimatedMeshSceneNode* RepairBoundingBox(IAnimatedMeshSceneNode* node) { IAnimatedMesh * mesh = node->getMesh(); aabbox3df box; for (u32 i = 0; i < mesh->getMeshBufferCount(); i++) { mesh->getMesh(1)->getMeshBuffer(i)->recalculateBoundingBox(); box.addInternalBox(mesh->getMesh(1)->getMeshBuffer(i)...

In my humble opinion, even if this feature would be very hard to implement, an engine that doesn't support bounding boxes resizing in its animation system is totally useless...

I have the same problem with .ms3d file!
Files .md2 don't have this problem, but they have too many limitations, as you can see in this thread: http://irrlicht.sourceforge.net/phpBB2/ ... hp?t=31047
Any suggestions?

try another mesh format... OK! Thank you! I'm using .ms3d file format, so I'd think to convert it to .md2, but I don't know if it is possible, because my mesh has more than 4096 triangles and more than 2048 vertices (I'm getting this error on converting it on MilkShape)... :?: Furthermore, I don't ...

Attach bounding spheres or boxes to some of the bones of the skin, as the bones move so will the spheres. This is how we've done it on all the games I've worked on. I have the same problem, can give us an example of it, please? I have a skinned mesh with bones inside and I want to animate it and ke...

OK! Thanks!

I use that code to create it:

Code: Select all

scene::ISkinnedMesh* mesh2 = (ISkinnedMesh*) smgr->getMesh("humanoid.ms3d");

Is it correct?

JP wrote: You can't create one yourself you just get given one from smgr->getMesh(..) if the mesh you're loading is of a format that uses skinning.

I have an .ms3d file, does it support skinning?

I have the same problem! What have I to do to solve it?
