TD maze

[Vamtiin]

Hi there, I am working on a TD and need to do a trigger that is something like...
a trigger that checks if there are more than x tower in the wideness and then it will autodestoy the last created unit.
Someone that knows anytihing of it ?¨

All towers is based on the "arrow tower" and have the same groundtexture.
A total of 9 towers wide is possible.

I will remove the attacking ability on the creeps and make it impossible to shut the maze since the creeps didnt go in the maze and instead smashed the towers...

trigger it with the event finish or starts construction, add all units of type structure (or whatever classifies your towers) into a unitgroup and count the unit. if the number of units in the unitgroup is 9 destroy the constructed tower

Well, wouldnt that include ALL towers and limit the towers to 9 for the player ?
What I mean is that I want a trigger that counts the towers in a wide line and if it reaches 9 it destroys the last constructed building.

This wouldn't work anyway.
You'd be able to block diagonally.

X = tower
# = nothing

X########
#X#######
##X######
###X#####
####X####
#####X###
######X##
#######X#
########X

Or.. Anything along those lines.
For example:

X########
#XXXXXXXX

Hmm... Okay, so is there anyone that has the solution to following problem:
The creeps in the waves attacks the towers but there IS a way through. I have set the collision size on the creeps to 0 but they attack anyhow. :banghead:
I really need to fix this problem... Anyone ?
