Im making a low poly fps shooter inspired by call of duty zombies mode, and i would like to add the wallbuy mechanic but have no idea where to start since i dont know much c#?
This one is fairly simple to do,
You can add a model of the weapon on the wall, add a collider over it.
Then you can do something like:
void OnMouseOver(){
if(Input.GetMouseDown(0)){
// Remove some money, give player the weapon.
}
}
This will be the easiest bet.
