Triggers

Well, these questions r on triggers so... How do you make it so you can't play it on single player? and also How do you make it so theres a cpu hero wandering around and is like a human?(kills enemys, picks up items, roams around) kinda like whats in COT Rpg

Also if anyone nos how to make it so trees never die and u can get lumber lumber all you want and the tree wont go away.

1. This is easy. Make a little trigger that runs around startup(1 or 2 seconds into game) and check how many players are playing. If the number is 1, then just defeat him with a message like you can only play with more than one person.

2. You can either try and write your own AI, or do a huge trigger AI simulation.

3. I believe that you could just do a periodic event and choose every destructable whos life != (not equal) to 100% and set their life to 100%. It would only have to be run every 10 - 15 seconds.

I also don't really know how that AI simulation thing works and doesn't it still work in single player if do that and someone makes a cpu in the game?

No, because you check how many player controlled players are in the game.

You first check how many players are in the game by using "melee game - create starting units" (this is the only way I know to make units for only the players that are actually playing, does anyone know an easier way?) and then counting the players that have a town hall at their start location, and then removing the town hall and peasants. Then you check how many of the players are human controlled with the "player controller comparison".

Check each slot. If it's a human player add it to a count variable and if the variable is = 1, end in defeat.

ok so how do u do the AI simulation then?

For the tree you can make a custom invurnable unit with the model of a tree.

No i still want to be able to mine from the tree just make it so the tree never dies and u can mine from it forever.

give the tree the max of life ( 99999 )
