It is possible to make script that will automaticlly destroy and then rebuild any of the buildings.
It only takes to press one button to build whatever you want.
Here is the script:

alias sentry "destroy 2; build 2";
alias dispenser "destroy 0; build 0";
alias entrance "destroy 1; build 1";
alias exit "destroy 3; build 3";
bind (button) sentry;
bind (button) dispenser;
bind (button) entrance;
bind (button) exit

Copy this whole text to your console and repleace the "(button)" fields with the button of your choice. If you want write everything one-by-one command, don't write ";" after every command.

Now, anytime you press the button you have binded it will directly activate Destroy and Build commands.This way you won't worry about switching weapons, everything is instant!

With normal wrench you want to use this to quickly set up your defense. Time in here is very important. Don't loose any second. Also if you know that your buildings will be destroyed you can quickly repleace them.


It is more usefull with Gunslinger. Everybody is annoyed when his mini sentry will be destroyed in the middle of fight and have to quickly repleace it with new one.With simply pressing one button that will build you new one with instant you won't worry about that.
Also, if your building is sapped you can't destroy it with "Destroy" command and thust you can't build new one.

If you will press Button that builds you teleporter entreace (or any other building) and you will taunt with action item (like High-Five), press that build button again while taunting and you wil be pleaced to "T" pose. You won't hold any gun but you can switch to other.This is funny when doing in public servers and everybody is wondering how are you even walking and why you don't shoot.


You can do one funny thing in MvM. If you gonna repeatly keep pressing "build button" and placing buildings, destroyed buildings will create broken parts (which acts just like medium ammopacks). After some time there will be brokens parts EVERYWHERE. Everytime I do this on some random server people are looking at me like shocked and asking me how do I do it (and sometimes calling me cheater lol).
