Hi All,

I have four (hopefully simple) questions:

1. Is it possible to play a sprite animation in reverse, aside from creating a new sprite with all the frames in reverse order?

2. In WME, what integer values correspond to boolean true and false?  Is 0 false and every other integer true?

3. If I define a variable in the beginning of a script associated with a room object (e.g. var object_property = SceneState.some_property), is the variable only updated when the scene is loaded?  Namely, even if SceneState.some_property changes during the course of the scene, would object_property not be updated until the scene were reloaded?

4. How do I change a Scene's default script directory?  I renamed the folder from "scr" to "scripts," but, whenever I create a new script in SceneEdit, it puts the new script in the "scr" folder (and creates the "scr" folder, if it doesn't exist).

Thanks for your help!

1, nope. You have to create separate sprite.

2, nope. As usually, 1 is true, everything else is false. (Usually you use 1 for true, 0 for false thanks to binary origin of boolean logic).

3, I don't know if I get it here, but are you trying to call a C like pointer to variable? Then, it's not possible. You would have update your variable whenever your Scene property changes. Why not use Scene object directly though?

4, Look at your WME distribution folder into folder template. There is defined what each action (entity creation etc.) performs, so you
can make your own template with script instead of scr if you are so inclined.

Hope that helps.

2, nope. As usually, 1 is true, everything else is false. (Usually you use 1 for true, 0 for false thanks to binary origin of boolean logic).

Not really, zero = false, non-zero = true. But of course, it only applies when converting integer values to boolean. WME uses a native boolean type for storing logical values.

3. If I define a variable in the beginning of a script associated with a room object (e.g. var object_property = SceneState.some_property), is the variable only updated when the scene is loaded?  Namely, even if SceneState.some_property changes during the course of the scene, would object_property not be updated until the scene were reloaded?

SceneState is a global variable, it retains the value for the entire game session. Scene variable changes as scenes are changed. Storing some property directly in Scene variable (Scene.Something = 1234;) is allowed, but the value is lost once the scene changes.

4. How do I change a Scene's default script directory?  I renamed the folder from "scr" to "scripts," but, whenever I create a new script in SceneEdit, it puts the new script in the "scr" folder (and creates the "scr" folder, if it doesn't exist).

The "scr" directory for creating new scripts in SceneEdit is hardcoded and currently it can't be changed.

Mnemonic: then we ran into bug in WME:

Code: [Select]

var test = 5;

if (test == true) Game.Msg("TRUE");
else
Game.Msg("FALSE");

This prints FALSE

while the following prints true

Code: [Select]

var test = 5;

if (test) Game.Msg("TRUE");
else
Game.Msg("FALSE");

Or is this on design?

[Mnemonic]

Well "5" is not equal to "true". You'd have to do something like

if(ToBool(test)==true) ...

[metamorphium]

That's why I was suggesting using 1 and 0 in the original thread to avoid this confusion, because

if(test) is for some people shorthand to if (test == true).  While the former works, the latter doesn't.

Ah, ok. Anyway, I would avoid comparing logical values with other types.
