fps_lock

If this flag is set, the time_step variable is locked to fps_max, regardless of the real frame duration. All functions using time_step - i.e. all speeds - will then become frame rate dependent.

Range:

on - time_step depends only on fps_max
off - time_step depends on the real frame rate.

Type:

var

Example: 

fps_max = 60; 
ifdef TEST;    // use this for test purposes only!
fps_lock = on; // time_step is now always 16/60 = 0.266 ticks 
endif;
