third person firing from turret issue

fLUnKnhaXYU · July 30, 2019

T3D version 3.9

Ive just encountered this situation

could someone explain What is happening here ? When in 3rd person POV , the turret gun seems to be firing in the reverse direction .

1st person , player not mounted , but turret is the control object .

3rd person , turret is the control object

player mounted to turret , 1st person

player mounted 3rd person

That is pretty cool. Off and on, I've been trying to get turrets working in general. When you say reverse, in which way is it reverse? I'm at work now but would like to see this working. Any chance you can post the code? I could check it out tonight.

Jason , If you're willing to look through this then , thank you and , certainly , have at it . Its mostly cut/copy/paste which

accounts for any resemblance to any sort of professionalism . Id like to add that , for the models , I closely followed the

deploy-able turret example to get a working AI turret , which I showed-off in the show-off forum recently , and from that , this

example . If you'd like , Ill put together a couple pictures of the modelling process and hierarchy tree . I'm still working on

it to see what it does and doesn't need in order to work .

Thanks, this should be enough to check. I don't think I need any models.
