I tried the plugin and the "unstable gravity" does work with the run on roundstart mode (amx_gravround 1). However, with the loop mode (amx_gravloop 1) it does not. I looked into the code, but my basic understanding of scripting got even worse over the time. If amx_gravloop is activated, every amx_gravstab seconds the gravity should change - but it does not. I thought there might be something wrong with the set_task in line 137 that is supposed to be the timer for amx_gravstab:
There are more set_task in the code that use the "a" flag, but they are set to repeat once. This set_task is not, so I changed it to:
and it looks like it does work now. But as I said, my very little understanding of scripting became even less - so I would like someone competent to look over the code and my change, and to tell me that my change will work fine and does not produce any problems. Thanks in advance.
