Irrlicht Engine

Thanks, I didn't know about the draw function. I was able to use that to come up with code that draws static text to a IGUIImage and then scales it up. It looks like crap, you were definitely right about that. Getting this method of text drawing to work with text boxes and list boxes would be diffic...

I am trying to devise a way of resizing/scaling text so that I can have a fully scalable UI. In fact, I already have almost everything having to do with ui scaling already finished. Everything except text. As we all know, you can only change the font to be used with static text. There isn't a fontSi...

I ended up finally getting entirely everything I wanted. I even successfully separated the pitch and yaw rotation so 1 bone could do only yaw and the other bone could do only pitch. This way dual point gimbal turrets work better. It just took a massive amount of brute force trial and error. I resort...

hold on, parentTransform.setTranslation(core::vector3df(0,0,0)) doesn't result in the same behavior as this parentTransform[12] = 0; parentTransform[13] = 0; parentTransform[14] = 0; parentTransform[15] = 0; i'll start trying both methods every time i change and check something. The following code m...

hmm, i had already tried separating them vs not separating them before posting that. What visually happens and the rotational axis values are often useless and inconclusive. (x and z axises are combined based on whatever the quaternion algorithms say to do and whatnot). In my above attempt (with com...

Do you know how to change the last row of a matrix to 0 like that in irrlicht 1.8? I think setTranslation() should do it. Is there a better way to do it? Thanks for the warning about scaling, I've been really careful to make sure nothing having to do with scaling ever happens in my project. Anyway i...

I'm using Reactphysics3d. It's ok, but I try to use irrlicht for rotations when possible because it has more stuff. In my experimentation, the absolute angular velocity reactphysics3d returns is less usable than calculating angular velocity by keeping track of irrlicht node angles. Iirc I tried rota...

i'm trying to make it so that a turret on a ship points at another irrlicht ISceneNode. The turret node is a child of the ship. The targets are at the same level as the ship, there is never a situation where a turret needs to target an item that the ship is a child of or that is a child of the ship....

Something occurred to me the other day. If it's not really possible to get the relative angular velocity of an object in physical space because math can't work that way, how does the gyroscope on my phone work? It can handle orientation relative to wherever "flat" is in x,y,z angles as wel...

welp, false alarm. I thought I had my position lag bugs fixed but I don't. My changes made it so that I can have an object on a moving ship and still be able to get the position of the object that is a child object in the ship and have it be accurate but I can't have an object be a child of that obj...

ok well i'm still working on it. getAbsoluteTransformation().rotateVect(physicsObject.getAngularVelocity()) doesn't quite work but it works certain edge cases. It's hard to test it and find exactly where it goes wrong because I also don't have a way to derive relative velocity which means no linear ...

Would it be possible to convert that getAngularVelocity() vector into a form that would actually work with rotateVect()? Your idea is the most correct sounding thing I've heard all day. How do I convert it to a 3x3 matrix? I believe (but haven't proven) that the units from getAngularVelocity() are i...

An idea I got while brainstorming is make 3 "virtual" angularVelocity sensors that are attached to the ship's scene node. One faces forward, one faces upward and one faces to a side. They then keep track of their current rotation along with whatever their rotation value in the last frame w...

I'm making a spaceship game. I'm using irrlicht for the graphics and reactphysics3d for the physics engine. In this game, the ships have "flight assist" which need to be able to hold yaw, pitch and/or roll angular velocities to a target. The problem I'm running into is there doesn't seem t...

it turned out that I wasn't quite running updateAbsolutePosition() often enough I guess. For some reason, when I added updateAbsolutePosition() into a loop within updateAllObjects() so that it updated the absolute position for every object when it copies the values from the physics engine to the sce...
