after Christmas I need a freelance unity programmer to build the core mechanics for a game prototype. I can provide the design document for the game as this is finished. I need 16-24hrs of coding in unity, just the core mechanics with placeholder stock audio and graphics (my team will be providing the final audio and graphics) - and I will be taking over the unity coding after you have built the core mechanics for the prototype. My budget is NZ$90-160 (max) I need the following elements: 1. entering a shop and attempting to buy items (including cigarettes) 2. walking around outside the shop and map creation 3. looking at inventory, 2 places to do this "at home" HUD and "back of field" 4. moving from place to place mechanic and "how time works" element 5. environmental changes and how this affects gameplay 6. side quests - getting beaten up, buying clothes (certain clothes might get you beaten up by certain cliques), beaten up character cannot enter stores until healed 7. detention - meet people you wouldn't normally meet 8. interacting with characters outside - talking to people (choosing from limited dialogue snippets to communicate what you want to discuss/negotiate) 9. skipping "outside-manouvering of character" to go directly to a location but sacrificing some time to do so 10. betting on fights 11. trading with other hustlers 12. stolen porno magazines - telling on the person who stole them (consequences) or buying and selling them (consequences) 13. painting miniatures as a service and getting paid for it 14. watching collectable card games and buying stolen cards (similar consequences to 12) 15. trying to negotiate with a npc to get them to buy cigarettes for you (because the dairy owner won't sell them to you, you don't look old enough)
