[Ace] How to make evented transition effect

じ☆ve冰风

Background :
This started from my project I'm working on. I wanted to create a seamless map change. But I don't want to go fadeout and fadein effect and change map in between. Then I was thinking, why not implement transition effect like how the transition implemented on map to menu screen and vice versa, but applied it on map? Then this idea come up. As a disclaimer, I'm not sure if this tutorial had been written somewhere else, so I hope it's not a duplicate tutorial.

Basically, we're going to do this :

Now, how?
While I said "evented", you obviously still gonna need two script calls, so it's not really a pure "evented", but hey at least you don't need external script to do this.

What you need to do is to put the event with this template.



Two script calls you will need.
Put this first
                Code:        

1. Graphics.freeze

复制代码

And this
                Code:        

1. Graphics.transition(duration)

复制代码

Duration is based on frame. So the smaller number is, the faster the transition will be.

Note that you will have to put the wait command right before the transition or else the transition will not happen.

For example on the gif inside the spoiler, I use this




You can also put a transition image. For example, I will use a default battle start from RTP file. The code will be like this
                Code:        

1. Graphics.transition(60, "Graphics/System/BattleStart")

复制代码

And the transition will be like this

Ok, so what can you do with this?
You can do other things as well, not always transfer map. Something like changing the thing on map. For example, change event graphics and/or rearrange the event position while the screen is being frozen, then perform transition after that. Or maybe you can do it while doing tile swap, and make a transition between in between.

Another implementation would be like this.



This does not transfer the map id, but it DOES change the map (or I'd say, something on game screen)

What you can't do with this?
The transition completely freeze the screen. So while perform transition, you can't walk, and everything else like event (parallel, autorun) will stop for a moment until the transition is finished.

Closing
Hope this little tutorial helps for people who use VXAce. I don't know if the equivalent function is present in MV. So you better ask people who expert in MV. If you have feedback, questions, or suggestions, feel free to leave a comment.
