Yikes, bad luck on the crash
If you set off a bomb without putting it down you'll be dead. What are you trying to do?
What do you want to set a bomb in the Editor for? Which type of bomb? Again, what are you trying to do? (Makes a big difference for the answer!)
What do you mean, make the player talk? Do you mean in a cutscene? Or do you mean an AI unit? Do you want speech sound files or are you just referring to the coloured text that comes up at the left hand side of the screen?
Sorry, I'm not being very helpful. But the more specific you are about what you are trying to do, the better we can help you.
I suspect that you need to learn about the commands
sideChat
globalChat
vehicleChat
groupChat
switchMove
playMove
Get the switchMove/playMove animations from the Unofficial command reference.
