some of these creatures are pretty cool. how would i go about exporting them from the maps and putting them in my own map? do i just copy paste or is there a better way of exporting? do i just copy the actors and units in the data manager?
The way I did it is to open the map file with MPQEditor and extrat the data xmls. You can then reverse the process to insert them in a new map. There may be a better way but this is pretty fast especially across multiple maps, and gets more so as the amount of data gets larger.
Yeah visually it's similar but the code is very different. I used a data driven approach which allows for a much closer integration of the various elements of the final unit. For example with this unit you can see it allowed me to make the DT swing his scythe rather than standing idle while the Zergling mount launches his attacks.
TPBH uses triggers which isn't really going to let you do any more than join one actor to another at a preset point. I agree that it looks similar but if anyone is annoyed I have to plead ignorance :P
