In a previous commodity, we showed how you can tin can motility a platform in Unity past using the office MoveTowards() and the function Mathf.PingPong(). You lot can find that article here. Another fashion to motion a platform is to usa an blitheness. This allows you to have some more complex movements fairly easily.
Create an animation for your platform in Unity. Commencement recording, and identify your platform in the position you lot want to starting time information technology on a keyframe. Then place it where y'all desire information technology to travel to on another keyframe. Finally, identify information technology dorsum where information technology started on a keyframe so that it loops.
How to Open the Blitheness Window in and Adhere an Animation to an Object in Unity
If you lot have never used information technology, the blitheness window is probably not in view. You tin can open information technology by doing the following:
- Click 'Window' adjacent to the 'Aid' push towards the top left of the editor.
- Towards the lesser of the list click 'Animation.'
- Finally click 'Animation.'
The animation window volition open and you can drag it to the position you lot want information technology in the editor. The window is shown below.
Select the platform gameobject y'all fabricated in the Bureaucracy window, and click the Create button in the Blitheness window. Information engineering science will prompt yous to relieve the animation, then brand sure you save information technology.
Subsequently it is saved, your animation window volition modify its wait. On the left, you lot'll see the proper name of the blitheness, and on the correct, you will come across a timeline. The timeline is where you will place keyframes. Note that 0:05 does not mean 5 seconds. it really means five/threescore seconds or .083 seconds. one:00 means ane 2nd.
The graph'due southward timeline is spread out fairly wide. You probably volition not be able to see much more than than about 1 second worth of time. To run beyond more of the timeline, with the Blitheness window selected, employ the roller on your mouse and rotate it towards y'all. The more you lot curl it toward you lot, the more than time on the timeline you will meet.
Side past side, brand sure your platform object is selected, and click the record button at the left of the Blitheness window. Place the platform exactly where yous want information technology to start in the animation. In my example, I will have information technology start on the left side of its road, so something like 10 = -5, Y = five, Z = 0.
Now, while the animation is still recording, click a time on the timeline where the platform volition be at the end of its route. Change the platform'due south position to where you want it to get side by side. In my case, I put it to 10 = five, Y = 0, Z = 0 at 1:thirty on the timeline.
At this betoken, if y'all did no more than to the animation, the platform would become from 10 = -five to Ten = 5 and just terminate. Only with a platform, yous usually want to it to go back and forth, so we demand one more keyframe.
Make sure the tape button is nevertheless on. Click a time on the timeline where the platform will exist dorsum at its starting position. Move the platform dorsum to its starting bespeak. My starting bespeak was Ten = -five, Y = 5, Z = 0 at 3:00 on the timeline. Finally, click the record button once more than to turn it off.
Click Unity's play button at the pinnacle of the editor and you should come across your blitheness first at one indicate, move to the adjacent point, and move back to the starting signal. It should repeat this forever.
So your uncomplicated platform route is completed. Very dainty for not having to write one line of code. If y'all demand to ready the platform to allow the thespian to stay on it while information engineering science moves, I recommend checking out this other commodity that as well discusses moving platforms.
Make a Moving Platform with Multiple Stops
Sometimes we need a platform to brand multiple stops. Using an animator to reach this is also fairly simple. In this instance, in that location will be four position the platform will motility to: data technology volition start at -5,five,0, then go to 0,ten,0, 5,five,0, 0,i,0, and finally dorsum to -five,5,0. Encounter image below for a visual of these locations.
To practise this, we apply an blitheness and add five primal frames. I put the key frame at 0:00 on the timeline at position -5,5,0, a frame at i:30 at 0,10,0, a frame at 3:00 at 5,5,0, a frame at 4:30 at 0,1,0, and a frame at 6:00 dorsum at -five,5,0. Bank check the image below.
This causes the platform to continuously movement betwixt the 5 locations. They don on stop at any ane signal. Nevertheless, if you lot wanted the platform to stay at a certain location for a moment, y'all tin can practise that. For case, nosotros could stop it at 0,x,0, the 2nd keyframe, for i 2nd, so permit information applied science to get to the third keyframe.
To do this, I would add together together a cardinal frame at ii:30 on the timeline and make the location of the platform exist 0,10,0. Because it was already at that position when information technology reached the 2nd keyframe, the blitheness will nonetheless run, simply information technology won't motion toward 5,five,0 until two:30 on the timeline has passed.
Animations permit for then much flexibility with moving objects. Recollect, you lot can also rotate and scale objects at sure keyframes to manipulate the movement and shape fifty-fifty more than. So practise a lot of experimenting with animations, and you may come upward with some very unique and stylized gameplay.
