I'm rather sure he meant creating in-game? Since you cannot create a lot of trees instantly (besides copying ofc) in the editor either.
Personally, I found a lot of trouble here too... Trees cannot be revived in-game... And if you kill them, they're still unwalkable due their footprint...
After trying to play with trees desperately I didn't found a single solution, besides removing them and replacing them. But this makes the spot they were still unwalkable... I also failed in editing the footprints.
So how did I solve it?
I simply created a unit with the model of a tree and another one with the model of a "dead tree". By doing this, I don't have to use footprints and thus a "dead tree" or a "removed tree" becomes walkable. Now, the collision size of an alive tree has a value, whereas the collision size of dead trees is zero and thus they're walkable (don't forget to set push rate to 0).
Now, all you need is a trigger to replace them on revive/kill instead of kill/revive functions.
I just got to watch the video because even though I was there I was trying to work out tech problems with the chat since I was the social media guy so I was distracted but check it out guys the video is super fucking great!
Looks like Google fixed whatever mistake that made the recipes on the site go crazy and we are no longer trending towards a recipe site lol - I don't care though because it motivated me to spend alot of time on the site improving it and at least now the content people are looking at is not stupid and embarrassing like it was when I first got back into this like 5 years ago.
They also were digging threw old shit at the sheriff's office and I tried to get them to give me the old electronic stuff, but they said no. They can't give it to people because they might use it to impersonate a cop or break into their network or some shit? idk but it was a shame to see them take a whole bunch of radios and shit to get shredded and landfilled
Signatures can be edit in your account profile. As for the old stuffs, I'm thinking it's because Blizzard is now under Microsoft, and because of Microsoft Xbox going the way it is, it's dreadful.
