I know I have to go on a brick and right click it then add the dialog object but what do I do after that? I know I have to go to the block thing but how do I add the text?
You must have a dialogchoice within dialogue for you to add the responsedialog and userdialog
(userdialog is what the npc/brick says)
(responsedialog is what the player responds)
so in order for your dialogue to actually work you must insert a dialogchoice and then edit the userdialog which is in the properties of the dialogchoice and then edit the responsedialog with what you want to respond with.
if you want a video tutorial click on this: http://www.youtube.com/watch?v=R_K24mh-X3A
Drag dialog onto head, go onto properties of the dialog and find "InitialPrompt" then put the text you want it to be when you click on the dialog.
