static value over multiple frames in vex based on time

[MoteOne]

Hi everybody,

i'm trying to get a random value every nth frame. For example on Frame 5, 10, 15 etc it should change but in between it should remain static.

i tried:

int t = int(@Frame%5);
float random=0;
if(t == 4){
    random = rand(@Frame);
    }
f@random = random;

 

and i just tested if I could append a random value to an array if @Frame%5, but it alwys removes that value after the condition is met.

2nd question would be how to implement a timer? for example over the next 5 Frames add a value to a variable.

 

Any advice would be awesome. Thx in advance
