Changing Event Images with Variables

[NeptuneTron]

Is anyone aware of a way to use scripting to change the image of an event? Specifically, I need to be able to designate the image for the event using a variable. Any ideas?

I use this for all my events.

var varId = $gameVariables.value(7);
var tId = $gameVariables.value(varId);
var eId = $gameVariables.value(5);
var ttId = $gameVariables.value(eId);
var eeId = $gameVariables.value(6);
$gameMap.event(eeId).setImage('Enemy' + ttId, tId);

If I remember right eeId is enemy ID, 'Enemy' is picture name then the + adds the variable to the end of it and tId is index of picture.

It is not with Script but i just wanted to mention it in case it helps:
Create several Eventpages and mark a Variable as Page Condition.
Page1 variable1 = 0
Page2 Var1 = 1
page3 Var1 = 2
...
Every Eventpage can have its own Character Graphic.
When you change the Variable, the Eventpage will change automatically.

Hi there!
You can change through script call the image of the event:

$gameMap.event(2)._characterName = "characterimage"

Also, you can change the current index that the event is using in this image:

$gameMap.event(2)._characterIndex = X

The first one must be a string(a word inside quotes), that has to be the name of an image that it is inside your img/character folder.

In the second one, you have to replace the X for a number of 0 to 7.

So, to use variables to change the images, you can set a variable value to a string through the script call field(without the file extension) in Control Variable operation. Then, you use this script call:

$gameMap.event(2)._characterName = $gameVariables.value(x);

And to change the index, you only have to set a number value from 0 to 7 in any variable you want, then you call the script call:

$gameMap.event(2)._characterIndex = $gameVariable.value(x);

I do not test changing maps to see if the image still prevails.
Hope it helps!

Thank you everyone for your excellent replies!

By cobbling together all of your replies and some other various information, I've managed to write a simple bit of code that will do this.

$gameMap.event(this.eventId()).setImage($gameActors.actor($gameVariables.value(n)).characterName(),$gameActors.actor($gameVariables.value(n)).characterIndex())

That looks complicated, but it's not so bad.

Let's break it down

$gameMap.event(A).setImage(B,C)

This is the basic function itself (Big thank you to glaphen on that one). Here, A is the Event ID of whatever event you're trying to change, and B is the filename where the image you'll be using to replace is located, and C is the index within the file of the specific image (Thanks to Eliaquim for that explanation).

this.eventId()

This is what you can use to determine the event ID (A) of any event, meaning that you can just copy this script into whichever event you want to use without manually finding the Event ID, or you can even use this in a Common Event (which I would highly recommend, as it will simplify your life greatly)

$gameActors.actor(D).characterName()

This returns the filename (B) for the image you want to use, where D is the Actor ID you want to use.

$gameActors.actor(D).characterIndex()

This returns the index (C) within the file image you'll be using, where D is the Actor ID you'll be using.

$gameVariables.value(n)

This is just a snippet of code that references the n-th variable, which I used to determine/select D. You always want to use the same variable number, but which number specifically used makes no difference. For instance, I used the variable 0006. You'll need to set the value of this variable appropriately, probably using another bit of code, or a common event.

In terms of setting the value of whatever variable you're using to something actually useful, you can use the "Control Variables" event command with the following script.

$gameParty.leader().actorId()

This will return the Actor ID of whoever is leading your party, to be used as D to define B and C.

I think that's pretty much the whole of it. Have a good day, or evening, or whatever time it happens to be.
