Can anyone help me out.

I'm having problems in this line

Untitled Trigger 002
Events
Unit - A unit enters Region 000 <gen>
Unit - A unit enters Region 001 <gen>
Unit - A unit enters Region 002 <gen>
Unit - A unit enters Region 003 <gen>
Conditions
(Owner of (Triggering unit)) Equal to hostileCreeps
Actions
Unit - Set the custom value of (Triggering unit) to (Custom value of (Triggering unit))

This line inparticulary Unit - Set the custom value of (Triggering unit) to (Custom value of (Triggering unit))

I can't manage to set it to Unit - Set the custom value of (Triggering unit) to (Custom value of (Triggering unit)+1)

How do I +1?

I've tried different options all around but nothing seems to hit the spot.

Thanks

Btw great guide. I think this is all I need to make my TD.

Use the Aritmethic integer part, allows you to do math between multiple integers

Thanks a million man. It worked.

But now I have different problem .

Untitled Trigger 003
Events
Unit - A unit enters Region 003 <gen>
Conditions
(Owner of (Triggering unit)) Equal to hostileCreeps
Actions
Unit - Remove (Triggering unit) from the game
Set livesCount = (levelCount - 1)
Leaderboard - Change the value for hostileCreeps in boardDisplay to livesCount
If (All Conditions are True) then do (Then Actions) else do (Else Actions)
If - Conditions
livesCount Equal to 0
Then - Actions
Wait 2.00 seconds
Player Group - Pick every player in inGamePlayers and do (Actions)
Loop - Actions
Game - Defeat (Picked player) with the message: Defeat!
Else - Actions

When a creep enters last region my lives goes from 100 to 0 .

I'm positive its -1 in the set variable of level count. What did go wrong here

Creeps being blocked?

What if someone purposely blocks the creeps and the creeps cant move and does not want to attack, what do i do?

Make it so that the path the creeps must go along is completely rock or another unbuildable surface if you don't want them to build on it, or do this for areas where you do not want them to build - Some TDs allow people to build on the path, some don't, I prefer the latter.

if its a mazing type td, give them an attack, then if they stop because they are blocked, they start rampaging around the maze destroying towers

tmpPoint

What bothers me is this line:
Set tmpPoint = ((Picked player) start location)

How do I set up so they spawn at multiple locations that aren't players' spawn point? (marked with an X on the screenshot)

Trigger:
• Set TempPoint = (Center of YourRegion &lt;gen&gt;)

Thanks for the help, but I fixed it already.
In case anyone else encounters the same problem, make a new region array containing all spawn points, and use the following action to spawn mobs:
Set tmpPoint = (Center of regionArraySpawn[(Player number of (Picked player))])

Still great after all these years.

I always remember this one as the tutorial which got me started with the World Editor.

Thanks!

I regularly refresh my photobucket accounts to keep the images in my tutorials from not displaying due to inactivity.

Plus I still get regular PMs asking me questions regarding how to trigger etc. because of my tutorials (which now gives a great oppurtunity to remind that if you have a question, please post it in the WEZ as a new thread, not PM me).

Oh, and happy New Year! (though I think nobody will see this)

P.S.

Woah, it's been almost five years.

Umm ... I need help. I agree this is the best to learn how to make a TD but, I am having troubles with the triggers.. Can you make it more descriptive because I just Can't seem to find the right triggers. For example take a screenshot for a specific Trigger and then show what part of the guide it is... other than that thank you! This is a very good guide!

Hi, I understand the beginning part, but from the trigger part, I get confused.. Can you explain it bit more or something else that will work?
