Text appearing & disappearing in the center of region

[Mashira]

Hello, so I made these triggers that should enable/disable a text to appear at the center of region.
Basically whenever a unit is entering the region the text should appear and when it leaves it should disappear.

Now, the problem is that it's buggy. Sometimes it works, sometimes it doesn't - text doesn't disappear or appear, etc. So far I tested it with only one unit but when I think about it, it'll get more complicated with more units, probably.

I'm not sure what it's all about. Perhaps there is a better way to implement this? Make invulnerable destructible with sign post model so the name simply appears over mouse hover? (just an idea that popped off my head at the time of writing)
Below are the triggers:

• WarningSignOn
  • Events
    • Unit - A unit enters Region 181 <gen>
  • Conditions
    • (Triggering unit) Equal to (Random unit from (Units in (Playable map area) owned by Player 2 (Blue)))
  • Actions
    • Floating Text - Create floating text that reads BEWARE! SPIDERS at (Center of Region 181 <gen>) with Z offset 0.00, using font size 9.50, color (100.00%, 100.00%, 100.00%), and 0.00% transparency
    • Trigger - Turn on WarningSingOff <gen>

• WarningSingOff
  • Events
    • Unit - A unit leaves Region 181 <gen>
  • Conditions
    • (Triggering unit) Equal to (Random unit from (Units in (Playable map area) owned by Player 2 (Blue)))
  • Actions
    • Floating Text - Change (Last created floating text): Disable permanence
    • Floating Text - Change the lifespan of (Last created floating text) to 0.00 seconds
    • Trigger - Turn on WarningSignOn <gen>

Entering unit is compared if it equals one random unit by player 2. If player 2 has more than 1 unit, there's chance it doesnt match. Use Player Comparison, OwnerOfEnteringUnit = Player 2

Also, to prevent other issues, you should store this Floating Text in a Floating Text variable and reference that throughout these triggers.

• Floating Text - Create floating text that reads BEWARE! SPIDERS at (Center of Region 181 <gen>) with Z offset 0.00, using font size 9.50, color (100.00%, 100.00%, 100.00%), and 0.00% transparency
• Set Variable SpiderText = (Last created floating text)

So you should replace anything using (Last created floating text) with a reference to this Variable instead. For example:

• Floating Text - Change the lifespan of SpiderText to 0.00 seconds

Note that regions can be a bit unreliable sometimes but these triggers should be okay.

Problem solved.
