[SOLVED] stepped uv transform with time var and random function

[romain.janil]

Hi, what is the best way to animates UVs in a stepped way (ie: not scroll each frame) ? Is it possible directly in the Uv transform field expression ?

Looking for a generic mechanism where I could offset UVs on various part of some maps randomly across engine.game.time.

Thx

Hi Romain,

The main idea is to transform float values to int and then back to float with rounding. You can experiment with the following UV animation equation:

vec4(1,1,round(time*10.0)/10,round(time*10)/10)

It would change UV position 10 times per second:

Thanks!

hi Silent, OK thanks, so more generally are all Math Common functions available in the expression field for UV transform, it's not really clear in the documentation?

Thx a lot

Yep, it's basically an UnigineScript expression, so you can use math as you want. We will update docs to cover this topic.

excellent Thanks a lot !
