Status of Features? #57

Does the engine also have:

-Programmable shaders? -Particle emitters/effects? -The ability to parent a 3D model to the camera (in an FPS game, showing the weapon/item the character is holding)?

I think if you added these three things (if they don't already exist) you'd be able to cover the "just enough" requirements of most games. Thank you!

Hi,

Programmable shaders is not in the short list. The internals support feeding different shaders, but to expose it, I need a material editor which I don't know how to implement a human usable UI/UX for.
Particle emitters are planned, just not for the next release. But since I don't have to meet some deadline, it might end up in it.
Attaching models to camera is the one I am working on right now. While working on it, I am finding bugs and architectural issues and fixing them. If you check out the latest commits, animation and jumping improvements are both caused by some testing models not handled properly by the engine :-)

If you want anything, please feel free to create feature requests too.

@enginmanap Regarding the shader issue, I was wondering if you could create a GUI window (with an editable text box) that basically allows the user to write the shader code inside of the editor? This would be a property you could select for any 3D scene entity, and then you could export the shader code (vertex/fragment) just like you would the XML map files.

Reading the shader code is easy, since Limon already reads it dynamically. If you want to test it, the shaders are under ./Engine/Shaders/. The hard part is determining which variables to pass when.

Currently I am loading 4 types of textures (Diffuse, Opacity, Specular, ambient), and 2 variables (RefractionIndex, specularExponent). Lets say you want to use normal maps. How are you suppose to set this in editor? That is the part I need to think about.

If you want to discuss this, there is a Discord that has 0 people in it, we can chat about it. The link is https://discord.gg/gqprbFd

I added the mentioned features to roadmap. Closing the issue, I will open ones for the features as they became feasible.
