Hi omnia games!
I could certainly see being interested in this integration and I know others would be as well as I believe UCC is the asset that can deliver the closest to a GTA-like experience in the asset store.
I know you didn't ask, but I'd be willing to pay:
$10 USD - Basic integration. Interact trigger on tank object jumps you into control
$30 USD - Animated entry integration. Character is animated likely via ability to climb up tank and enter it.
$50 USD - Advanced animated entry and more. Character has multiple animations for entry from sides, front, back, and possibly even as an air drop (parachute or jump off building onto the tank). Tools to easily modify entry / exit abilities to fit custom or third party vehicle meshes. Additional features like animation to pop out top with gestures or to fire side arm. Various camera presets. Various abilities like firing different types of weapons, tossing out grenades, distributing and receiving damage including splash damage and decal options, enemy AI (Behaviour Designer?) including running up and placing sticky bombs or sabotaging treads.
For my project, I implemented
Edy's Vehicle Integration with Third Person Controller Version 1. It was a simple integration that used an interact to jump you directly into the Edy controller and had an exit button to pop-out, but it was a more difficult implementation than I originally anticipated. I was working on adding entry and wanted to create my own IK driving with Opsive in Edy's Vehicle Controller or implemented
TURNTHEGAMEON's IK Driver Racing Avatar, Vehicle Controller & AI. I would pay $10-20 for a basic UCC integration with Edy's with basic entry and exit. This would increase with the addition of hijacking 'ala GTA (~$50ish) and the inclusion of IK driving (~$60ish) or easy integration with TURNTHEGAMEON's asset (~$30-40ish)
Hope this information helps and please let me know if you make any progress on this! I'd certainly be an early adopter. I had no intentions of having tanks in my game, but seems like a fun late game activity. Other vehicles are a must have as my game is like a scaled back and more grounded / comical GTA type game.
