How to move a unit in a line...

[Cweener]

Problem solved by:
darwin & MortAr-
I want to move a unit (target of a spell) towards another (the caster) over time.
I was wondering how to do this because I don't know, but I think it involves math, which I find highly annoying.

Bad representation of what I want

+rep will be rewarded.
Also, if you'd like to teach me what the hell things like "cos" do, that would be great.
(if any are needed)

This may or may not help, but here's what I'd do:

Make a variable for the caster and the target unit. When the spell is cast, assign the target and the caster to their variables, then turn on a trigger that is initially off. Call the Trigger "Repeated move" or something like that.

Event - periodic, every .1 seconds
condition- none
action-
Move Target instantly to position of Target offset by 10 toward the angle between Target and Caster.

If Distance between Target and Caster < 100, turn off this trigger.

Sorry I don't have all the words right, but that should be the general logic. Hopefully it'll get you started. If it's too fast or too slow you can change the "10" above.

• Trigger
  • Events
    • Time - Every 0.03 seconds of game time
  • Conditions
  • Actions
    • Set loc[1] = (CASTER)
    • Set loc[2] = (TARGET)
    • Set angle = (Angle from loc[2] to loc[1])
    • Set loc[3] = (loc[2] offset by 10.00 towards angle degrees)
    • Unit - Move TARGET instantly to loc[3]
    • Set distance = (Distance between loc[1] and loc[2])
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • distance Less than or equal to 100.00
      • Then - Actions
        • Trigger - Turn off (This trigger)
      • Else - Actions
    • Custom script: call RemoveLocation (udg_loc[1])
    • Custom script: call RemoveLocation (udg_loc[2])
    • Custom script: call RemoveLocation (udg_loc[3])

Thanks to both of you.
I'll have to convert it to JASS, but I'll use it. Thanks MortAr.
And darwin, that would work but I didn't want a whole other trigger.
+rep to you both.
