I don't quite understand how to use this command, what I'm wanting is to have my engine perform as many screen refreshes as possible but make the physics simulation run at a constant rate (but allow for variance like slow motion for cut scenes).

Has anybody implemented this yet?

I know the voices aren't real, but they have good ideas!

If you navigate to "Projects -> Demos -> Rigid Body -> Fixed Rate Timing" you will find an example that show how to use the command. It works very well actually

This example uses the command phy set auto fixed timing

I have just looked through all the projects too and didn't see that!

Cheers The Nerd , how I missed that I don't know

EDIT: Yeah fixed rate, I'm wanting variable rate and independant of the FPS.

See the syntax for the command is



But what does it all mean? Like the maximum step param 1.0 / 60.0
is that 60 updates for second??

EDIT:

Cracked it, the best way I have found to implement slow mo taking into account the fps is:

[PSEUDO CODE]
max_timesteps (default 1.0 / 60.0)
max_iterations (default 8)

if SlowMo
phy set timing max_timesteps / screen fps( ), max_iterations
else
phy set timing max_timesteps, max_iterations
endif
