Warcraft map editor trigger notes

1. Cyclic operation in unit group , Invalid use delay

For example, select all units in the map , And one unit will output “111”, And output after one second delay “222”, The result is that there are 6 A unit of . Instant output 6 individual “111”, And the delay has no effect , also “222” Will not get output

And for for The delay in the loop is useful

2. The one that triggers the command “ asynchronous ” Operating characteristics

When using trigger to give instructions to units , No matter whether the unit has finished executing the instruction , Trigger will run down . It is a bit similar to asynchronous operation in programming language .
For example, release the water element skill after the mage on the map moves to the center of the map , If you write this trigger directly , Then the Archmage will have no time to move and directly release the water element .
