Spirals in WC3

[bowser499]

Hi all...
Say me, how to draw a spiral using loop, X and Y?

 

[Ayanami]

By X and Y, do you mean using coordinates? So, I can't use locations?

You don't use X and Y coordinates. You use a polar off-set from the center's location and slowly decrease the off-set while rotating the angle. In addition to this, you can use height to make the spiral third-dimensional. A loop can be used to create this instantaneously, multiplying with the loop's integer variable for the increments and decrements.

This doesn't use X and Y though, but polar offset.

• Spiral
  • Events
    • Unit - *UNIT* Starts the effect of an ability
  • Conditions
    • Spell being cast == *YOUR SPELL*
  • Actions
    • For each (Integer A) from 1 to 108, do (Actions)
      • Loop - Actions
        • Special Effect - Create a special effect at ((Position of (Triggering unit)) offset by ((100.00 x (Real((Integer A)))) / 12.00) towards (10.00 x (Real((Integer A)))) degrees) using *YOUR SPECIAL EFFECT*

Increasing the end number in the for loop(currently 108) will make the spiral longer. Decreasing makes it shorter.

Increasing what you divide by(currently 12) will make the spiral tighter.

You can use other formulas too I guess, as long as you have Integer A in some way in the offset and degree field.

Note that you should set the center location before the loop and set the off-set location in the loop to avoid leaks. The above trigger leaks 216 location handles and 108 special effect handles per cast.

Oh right, not using the WE for a long time does that to you
