i want trigger event after every 3rd time.

for (i = 0; < 5000; i++) {     // when == 3, == 6, == 9 etc.     if () {       trigger();     } } 

i can't figure out how represent in code, brain stuck.

unless write: if == 3 if == 6 etc.

but write millions of these since unlimited.

you could...

• increment i 3, not 1
• use modulo check

so

for (i = 0; < 5000; i=i+3) { ... } 

or

for (i = 0; < 5000; i++) {     // when == 3, == 6, == 9 etc.     if (i % 3 == 0) {       trigger();     } }
