Maybe you can use the API linkto get the translation of camera and object to calculate the distance.

Hi berdon,

there's the method set_fps_callback. The callback executes every frame and gives you the actual fps value:
var m_main = require("main");

m_main.set_fps_callback(function(fps_avg, phy_fps_avg) {
    console.log("current fps is", fps_avg);
wow, I get it. Thanks, Ivan. And another question, can the fps be set?

OK, thanks, dear Will. Can I get the fps value in the scene? Because I control the bones action with the function
set_bone_tsr_rel(armobj, bone_name, tsr)
, so the speed of action is relative with the fps value.
So I need to know the fps to change the speed of playing.

Yes, but I still don't know how to set the fps in B4W, it changes in different devices.

Hi, everyone, the default fps in my b4w html is 60, but sometimes the fps may jump to a low value, and when the fps jump to a low value, the bones animation may be played slowly .
So I want to set the fps to a static value, for example 24.
