The Animate Command


    animate [tag=tag] [mask OR nomask] object-name animation-name imagecount framecount framerate [framelist]

Note: [] denotes optional arguments.


The animate command assigns an animation to the object. It is by far the most complex and probably least understood action command.

The optional tag argument specifies the tag number of the polygon on the object to apply the animation to. If omitted, the animation is applied to every polygon on the object.

If mask is specified, the animation is masked, and Outerworlds will attempt to download and apply a corresponding mask file for each texture in the animation sequence. The nomask option explicitly marks the animate as not masked. By default, animations are not masked.

Important note: The behavior of the animate command has changed beginning with Outerworlds 3.0! By default, animations are now not masked. If you have an animation that uses mask files, you must now explicitly specify the mask option.

The object-name argument specifies the name of the object to apply the animation to. This argument must be specified. If the animation is to be applied to this object, specify the keyword me as the object name. Object names are assigned via the name command.

The animation-name argument specifies the base name of the textures to be used in the animation.

The imagecount argument specifies the total number of unique textures in the animation.

The framecount argument specifies the total number of frames in the animation sequence. Note this does not have to be the same as imagecount since a given image can be used more than once in an animation sequence.

The framerate argument specifies the time in milliseconds between each frame of the animation. Note that low numbers for the framerate may cause the animation to drop frames in order to keep up on slower systems. A framerate of 0 means animate at the same rate as the browser's current framerate.

The optional framelist argument allows you to specify the order of images to be displayed in the animation. This argument must be specified if imagecount and framecount are different. The default frame list is 1 through imagecount.

Historically the animate command has been used most often for the purpose of placing a single static texture on an object. Please consider using the more efficient texture command for this purpose.

Note that the animate command will not work predictably on objects that do not have UV texture values specified for the vertices of the object.


    create animate mask me jump 5 9 100 1 2 3 4 5 4 3 2 1, astop; activate astart off

This action triggers a 9 frame animation called "jump" when the object is clicked on. The animation runs at 10 frames per second (100 milliseconds between frames). Note that while there are 9 frames in the animation, there are only 5 images since the first 4 are reused again on the way back down. The texture files for this animation will be named jump1.jpg, jump2.jpg, up to jump5.jpg, and the mask files will be,, up through

In this example, note the use of the create trigger combined with the astop command in order to set up the animation and stop it at the first frame. The activate trigger combined with the astart command tells the animation to start running when the object is clicked on.
