Hi. I just wanted to make some kind of thing that would fire a block down at a certain speed and would then go back up, by using vectors, but I do not know how vectors reacts when added to a location. The movement would be the exact opposite of when you throw something in the air, with the exception that the second part of the movement (when it goes back) would be slower than the launch. It would be in limited time, and 1/3 of the time would be used to go down to a certain postion, then the remaining 2/3, the block would go back up to one block upper than the starting postion. So, anyone knows how I could do that ? Or just tell me how vectors reacts with locations. By exemple, if my location is (50, 50, 50) and I add the vector (0, -1, 0), what will the final location be ?
