No worries! Extremely glad it is even possible. I found one other LUA npc spawner that worked but required that the player be inside of the vehicle. Worked well with the juiced vehicle spawner till I found out that certain parts of the game would crash due to that NPC spawn mod (Jailbreak was completely unplayable). Very awesome mod! As a previous user commented, having the options on screen to select is absolutely amazing!
Let me know if you need any help testing anything. Happy to help! Very eager to try this out once the spawned NPCs fight. Would be great too if there was an option to make them invincible.
