Yea I was thinking both of those as well, but both of them check out, and on top of that the tentacle isn't sticking permanently, just until it finds another target. It's as if I have the event wrong somehow. IDK I've been working on this problem for a while now, maybe you should take a look. You'll probably take one look and go "Oh yea here's your problem." Ignore the size of the Uberlisk, I made it smaller so I could better see the tentacles, since I don't have collision with them yet.
Dude, one word. Amazing. I take a look at some of the stuff in the tutorial and say "Wow that would have taken me quite a while to figure out." But some of it is so obscure, so outrageous, I would not know where to begin to find it on my own, and I have to wonder how on Earth did anyone figure it out? What strange unseen force led you to these epiphical spurts of genius? I can't pin whether you're psychic, an amazing gatherer of knowledge, or the luckiest man alive. Did you have help, gather the information in bits and pieces from others, or did you just swan dive into the searing pit of lava called the data editor and burst forth holding a prized trophy of knowledge? Truly, you have saved me a lifetime of research and experimentation, and for that I thank you kindly.
Now on another note, @BrotherLaz, try making both weapons, then under the options for each weapon the unit has, make sure the "Linked Cooldown" option is unchecked, then just check it for each of the weapons you have. Then make the "Damage Point" for both weapons different from each other. I haven't tested this, nor had a chance to experiment with it yet, it's kinda all theory I got from the tutorial, so don't expect a miracle. :P
Also, I seem to be having trouble with the tentacles. When they attack they stretch fine to their target but stick to wherever they attacked. When they attack again however, instead of staying there and "wiggling" they just stretch over to the next target, attack it, and stick again. Everything else works fine but it's obviously weird to have the spine stretch across the field, as well it seems to have adverse effects on the targeting AI. Took a look over everything and tried to find where some kind of screw up happened but I must be missing something, any ideas?
