Title: About sprite animation
Post by: Krosad on May 04, 2011, 07:30:08 PM

Hello!

How work Play() and Reset() ?

I have sprite with no loop animation, and i need play it on "LeftClick".

Can't you simply use entity.PlayAnim() ? Using the sprite scripting methods is an advanced technique and isn't necessary for everyday use.

How to stop animation at a certain frame?

You'd need to attach a script to the sprite and handle the 'FrameChanged' event in it.

Code: WME Script

1. on "FrameChanged"
2. {
3.   if (this.CurrentFrame == 10) this.Pause();
4. }
5.

Hi,

 I`ve got some problem with sprites.

I create noloop anim sprite in scene_init.script.

Code: [Select]

global indicator = Scene.GetNode("indicator");
global indicator_sp = indicator.GetSpriteObject();
indicator_sp.Pause();

.. then in indicator.script

Code: [Select]

on "LeftClick" {indicator_sp.Play();}
After animation, indicator sprite change color from green to red.
Then actor goes to another scene and back, indicator is green again (!?).
How to fix this?

I still trying to solve this problem
i add global variable ind_act = 1 if sprite was animated.

in scene_init.script

Code: [Select]

global indicator = Scene.GetNode("indicator ");
global ind_act;
global indicator _sp = indicator .GetSpriteObject();
if(ind_act == 1)
{
indicator _sp.CurrentFrame = 6;      // 6 - last frame
indicator _sp.Pause();
}
else indicator _sp.Pause();

i thought it must work, but WME give fatal error.

Hi,

first of all, when talking about errors WME throws, please also quote the error here. :-)

indicator _sp.Pause();
}
else klawa_sp.Pause();

From what I can see immediately: you have a blank in your variable name between "indicator" and "_sp", that shouldn't be there. This will surely throw a fatal compile error.

i did a blank, when i wrote this post, in scripts no blanks.


about errors WME throws. WME just don`t respond on Esc and i had to used ctrl+alt+del.

Code: [Select]

I think I found what It was.
Sprite must be set on next-to-last frame.
