Camera - mouse scroll

Hi!I have a question for Camera code!
When I lock camera to a unit,I was change Distance to target with value 2000!(Example is it!! )But when I scroll mouse or press Insert or Delete,camera is change Distance to target with default value! I want when I scroll mouse,my camera don't change distance to target to default value (1700~1800) that value will change to my value(2000)!
Please help me!Thank you so much!

Periodically update the distance to target, every 0.10 seconds or so should be fine

yeah, it's messy (ingame) but your best bet.

I used a TriggerSleepAction to fix this problem, never messed up for me.
