I have a question
I would like to add a sprite blur effect, when the object is moving. The higher the speed, the bigger the blur. Is it possible to achieve this programmatically ?
I have a question
Youd have to search and learn about render targets. Although im not the best person to give aid about, for i have tried in the past making something similar but didnt quite achieve it. But i think that for something like that there might be an already existing extension.
Hi @FredZX !
What you want to achieve is most probably a motion blur. I once adapted an implementation of motion blur from shadertoy (Shader - Shadertoy BETA) as a fragment program for a sprite to Defold:
You probably want it rather to be aplied to everything on your screen, so you might render your scene to a render target (a separate, internal buffer/texture) and then perform this motion blur as a postprocessing when drawing this render target to a quad (simplest plane, a geometry to which you assign a texture) and this quad will fill the screen. This is the most common post-processing pipeline in Defold, let us know if this is understandable to you or you need more explanations
You might get to know how to draw to an offset buffer / render target and to quad filling the screen after watchin my video:
or reading official Defold example:
After understading how to make post-processing with this technique - let us know how are you familiar with GLSL and if you can adapt the motion blur example to your needs
I’m not familiar with this technique, but I’m going to try it
I will be experimenting with this, maybe I will come with some solution, but please don’t rely on me, it could be that I will get it done quickly or after ages, as I rarely have time for such experiments, sorry!
But if you will try and get stuck on anything, let us know and we will try to help
