What tutorials are most needed?

[Vow]

What programming challenges do you notice yourself or other developers struggling with most often?

Looking to create detailed tutorials on advanced topics. Render script from scratch, 2D and 3D camera functionality, SPIR-V shaders, etc.

I enjoyed making the SPIR-V tutorial, so future tutorials would be similar in detail and style:

Tutorial: Basic SPIR-V Shaders with Custom Material

This is a simple tutorial for anybody who wishes to take advantage of Defold 1.9.2’s SPIR-V shader update. The only prerequisite for this tutorial is that you’re familiar with writing basic GLSL shaders for Defold. I’ll be outlining the process for creating a simple color-fill effect, demonstrated in the following GIF. [Untitled Project] The white rectangle (dubbed a “brick” in this tutorial) is a sprite with a custom material, vertex shader, and fragment shader that conform to SPIR-V . The r…

Need faster shader water - sea, for big 3d location

And more any shader vfx, particles

Excellent initiative! Just by looking at the forums today I see there’s multiple questions that could be potential tutorials:

I think even a list of really small examples of “how do I do X?” can be useful. According to the survey we lack examples, big and small

I did notice that on the feedback survey. Maybe I’ll try that too.

I wonder what the best place is for written tutorials though. The forums are nice because they seem to be the central place for knowledge and resources, but maybe there’s somewhere else that might be better?

Forums sure, but we can add them here as well:

Defold tutorials

I thought of something that could be interesting, not sure how possible it is though. A font shader that does a moving “golden sheen/shine thing” (moving gradient?) across the text.

Here is my latest challenge: I would like to animate a texture on a single face of a model. This model is a basic cube, and I want to animate its face from time to time, similar to using a sprite from an animation sheet (atlas). (I don’t want to use decals.)

Also, I don’t want to change the texture, so every animation should be within the same material texture. Something like this (with the middle showing the UV texture):

I have no idea how to do this right now(I know but I don’t ), but I would really appreciate some insights or a tutorial.

Like this perhaps:

What about common particle effects such as smoke (fire) and vapor (water). There are a lot to explore with particle effects, lots of parameters can be tweaked, and the curve editor too! How to do that to achieve common objectives?

EDIT: individual settings are easy to understand by themselves but how to combine them in efficient ways to achieve some global effect is basically what I would suggest we learn from some particles effects tutorials.

Postprocessing! I’m currently looking for an updated tutorial and it’s harder than I expected!

[britzl]

We plan to make this into the next community challenge. We will prepare an example of how to create a post processing effect and share that along with the challenge.

I understand the shader part, but the render script puzzles me a little bit, which gets worse when using plugins like ortographic camera
