Irrlicht Engine

Symptom: After implementing the above changes, RotationAnimators stop rotating their nodes. Cause: RotationAnimators keep track of the time at which the last call to AnimateNode() took place. This is so that in the next AnimateNode(), the animator knows how much time has passed, and knows how much t...

I should've mentioned that this change would also help splitscreen/multi-window rendering as presented in the split-screen tutorial. In that tutorial, one renders to each of four screens by calling drawAll() four times. This means that each drawAll will show a world that has advanced a few milliseco...

For some applications (e.g. simulators) it's useful to be able to specify the next frame's world time, so you can control what time eventually gets fed to the ISceneAnimators' animateNode() function. I suspect it'd be useful for games as well, such as when you want to slow down or speed up the world...

I posted this problem, and the necessary fixes to matrix4.h, in the bugs section:
http://irrlicht.sourceforge.net/phpBB2/ ... highlight=

The scale and rotation-related functions in core::matrix4 all seem to assume that a single matrix4 will never represent both a rotation and a scaling operation. This is a pretty risky assumption, especially if someone's trying to get an ISceneNode's global rotation using: vector3df absRotation = myI...

So, the problem is that matrix4 doesn't factor out the scale when calculating getRotationDegrees(). Shouldn't this be classified as a bug? This means that if one wants to find the absolute rotation of a node using myNode->getAbsoluteTransformation().getRotationDegrees(), one has to first make sure t...

When I don't draw any gui objects (namely, some on-screen text), my textures render incorrectly, as below: http://mrl.nyu.edu/~mkg/public/irrlichtPosts/yellowMonoScreen.png Note that some textures, like the skybox and leaves, do appear correctly. Anyway, below is what it's supposed to look like. I g...

Are you sure that it's those two lines you posted that cause the 6 second pause? I know that for me, my program pauses for a good 18 seconds when building the OcttreeTriangleSelector. For debugging purposes, I just use a regular triangle selector instead, which loads pretty much instantly (but gives...

So, here's my subclass of CCameraSceneNode that rotates its point of view when you rotate the node. MountableCamera.h: #include "irrlicht.h" #include "CCameraSceneNode.h" // Like the standard ICameraSceneNode, except when this node rotates, // so does its view direction. Hence, i...

I just discovered that rotating a camera node doesn't change its field of vision. Is there a way to get it to behave in the expected manner? What I'm trying right now is to write a subclass of ICameraSceneNode that checks its absolute rotation during OnPostRender and changes its FOV accordingly usin...

Awesome; that seems to have fixed it.

Thanks!

For what it's worth, using EMT_TRANSPARENT_ALPHA_CHANNEL doesn't cause this problem; just EMT_TRANSPARENT_ALPHA_CHANNEL_REF.

Hmm... I want to be able to set up collision detection, but later turn off the collision detection if I need to teleport. Your suggestion, if I understand it correctly, would work if I only needed to teleport at the outset, then could turn on and leave on collision detection forever after that. -- M...

Is there a handy way to temporarily disable collision detection on something (either the world or the robot/camera) after having added it? My situation is that I have a robot with a bunch of CollisionResponseAnimators attached, roving around in a quake map. If I want to move (teleport) the robot to ...

I had the same problem (in addition to this one) in another quake map when I switched to Irrlicht 0.10.0. Also using linux & NVidia (ubuntu, GeForce Go). I reverted to Irrlictht 0.9 as well.
