Make your thread names more descriptive so other can find your answers in future. I have just developed what you want, its not that simple but download these scripts and put them in your script bank then follow these instructions.
Ok for this to work you need 3 componants:
*A trigger zone.
*The barrel you want to explode.
*Another small Fpsc object to use as a detonator.
*Now place your trigger zone, and then change its main script to appearifactivate (attached)
*Set the if used propertie to the name of the small object you are using as a detonator
*Now place your barrel to be exploded and your detonator object next to each other.
*Right click on your detonator to access its properties:
*attach detonator as the start/appear script (attached)
*make sure its set to dynamic
*set spawn at start to "NO"
*set its strength to "1"
*set its physics force damage to "9999"
apply the settings
*Right click on your barrel to access its properties:
*attach barreldestroy script as the the destroy script (attached)
*make sure its set to dynamic
*make sure explodable is "yes"
set its strength to "1"
*Place your barrel where you want it
*place your detonator inside the barrel out of site
Your set run your game and watch the fun
Thanks
