How do i make it so a unit within range of unit(arrow) take damage the unit(arrow) is going very fast until it reaches the end of the map and gets removed

permanent immolation? or use a trigger

store the "arrow" in a variable when its created

• Events
  • Unit - a Unit comes within 300 of "arrow"
• Conditions
  • triggering Unit is owned by an enemy of owner of "arrow"
• Actions
  • Unit - cause arrow to deal 100 points damage to triggering Unit of damagetype.....

is the basic idea, also not MUI yet, maybe try immolation first

immolation is ineffective if the arrow moves quickly and you want a small area of effect. for an MUI system, you need to store arrows in a unit array, and use Loop Integer A periodically (every 0.04 seconds) to select all units within range of an arrow, and damage all these units with the trigger.

make sure to use unit groups and remove leaks, otherwise this will lag your map to oblivion
