I was wondering, im making a mission where you have to find a truck carying a diplomat and a bomb hidden in it. I was wondering how to use a timer (i know ofp has the capability) and make the truck explode on completion of this timer. This would be a really neat effect Help me please

Thanks a ton. They work gret

Is there any way to increase the magnitude of the blast? or is there a larger explosion i want it to be utterly chaotic thanks!
