Custom Animations¶
File location
/assets/minecraft/optifine/anim/**/*.properties
Custom Animations allows all textures to be animated, regardless of type and purpose.
Important
For block and item textures, including CTM and CIT replacements, continue using Mojang's mcmeta method instead.
In Minecraft 1.5, Mojang added the ability to animate any block or item texture (originally a feature provided by MCPatcher). However, there is yet no way to animate other textures like mob skins or GUIs. OptiFine fills the gap enabling any rectangular area of any non-block or item texture to be animated.
This includes even textures specific to other OptiFine features such as random mob skins or skyboxes.
To build an animation, first choose a texture and determine the X and Y coordinates, and width and height of the area to animate. Create the animation as a vertical strip of frames.
The width should be the same as the width of the area to animate. The height should be a multiple of the animation area height.
Multiple non-overlapping parts of the same texture can be animated by using the same to value with different from, x, y, w, and h values.
They can even have independent timing and frame order information.
Emissive animation is also possible, see Emissive Textures.
Properties¶
Note
duration, interpolate, skip, tile, duration are optional, rest are required
from¶
Path to source texture of the animation to display.
to¶
Path to destination texture to replace and animate.
x, y¶
Coordinates of top-left corner of the destination texture to animate to. Normally, this is 0, 0.
w, h¶
Width and height of an individual animation frame.
duration¶
Duration of each individual frame, in ticks. For reference, there are 20 ticks in 1 second.
interpolate¶
Whether to interpolate between each animated frame.
This furnace has an interpolated animation; focus on the fire inside.
skip¶
What frame number to skip/ignore during animation.
Important
Frame numbers start at 0, not 1.
tile.N¶
N is positive integerWhat frame number (starting from 0) to display at the N-th tick.
N can be greater than the number of frames.
duration.N¶
N is positive integerDuration in ticks to display tile N for.
This only applies to tiles for which a tile.N is declared.
Example¶
Rainbow squid¶
from=./glow_squid_glow.png
to=textures/entity/squid/glow_squid.png
x=0
y=0
w=64
h=32
duration=1
interpolate=true
skip=2
Note
See the Syntax document for how to specify paths to texture files.
This creates an interpolating animation that plays each frame in order from top to bottom once for one tick (1/20th second) each and then loops infinitely.
Frame order and timing¶
Each custom animation may specify its animation speed and frame order. In the properties file, add a series of entries:
tile.X=Y
duration.X=Z
X starts at 0 and represents the order of animation frames based on tick.
Y is the tile number in the animation frames, the first tile being 0, the second 1, etc.
Z is the duration that frame should be displayed, in game ticks (1 tick = 1/20 second).
If omitted, duration is assumed to be the default frame duration, or 1 if not configured.
For example, suppose the animation file is 16px x 48px, at 3 frames. To make it run on a 5-frame cycle with a pause in the middle, the properties file might look like this:
tile.0=0
tile.1=1
tile.2=2
duration.2=5
tile.3=1
tile.4=0
The animation happens in this order:
Frame 0: Display animation tile 0 for 1 tick (default duration).
Frame 1: Display animation tile 1 for 1 tick (default duration).
Frame 2: Display animation tile 2 for 5 ticks (duration=5).
Frame 3: Display animation tile 1 for 1 tick (default duration).
Frame 4: Display animation tile 0 for 1 tick (default duration).
Go back to frame 0.
Total: 5 frames over 9 ticks.
