that means your video card detail level is set too low to see the weather effects.
you need to check that your graphics settings are high enough in the game (see the video card options via the F10 menu)
since your using a school computer, they may not have purchased very good video cards there, in which case you should not expect to get high quality graphics in any game you play.
only ONE of the events listed has to become true for the trigger to fire.
For conditions:
ALL of the conditions must be true for the trigger to fire.
Allow me to attempt to make your thing work:
FIRST STEP: make a region of size 150 x 150 around the villager(male)019. Call it, say, 'villager_region'.
TRIGGER 1
event: [unit enters region]
A unit enters <villager_region>
action: [set variable]
set <within_range> equal to true [within_range is a boolean]
TRIGGER 2
event: [unit leaves region]
a unit leaves <villager_region>
condition: [integer comparison - count units in unit group]
number of units owned by player matching [boolean comparison - unit in region] <villager_region contains matching unit equal to true> equal to 0
action: [set variable]
set <within_range> equal to false [within_range is a boolean]
TRIGGER 3
event:
Player 1 enters chat message hi exact match
condition:
<within_range> equal to true
action:
do something
Sorry if it seems really complicated, but what you are (probably) asking isn't the easiest thing to do.
Tip: Get trigger 1 and 3 working first, worry about trigger 2 later on.
I do know this - xenforo dropped the ball by not keeping the vbulletin reputation comments as a feature. The loss of the Reputation comments data when we switched to Xenforo really was the death knell for the site when it came to all the users that left. I know I missed it so much and I got way less interested in the site when that feature was gone and I run the site.
I'm on a page about incorrect corrections, and spent the better part of like two hours trying to get someone to understand that -5^2 = -25, not 25, and then that post had comments get reposted because that group is self sustaining, and that person was in turn trying to explain what I just explained to them. And I'm taking that as a victory
