Texture Sheet Animation module
A particle’s graphic need not be a still image. This module lets you treat the Texture as a grid of separate sub-images that can be played back as frames of animation.
Propiedades
| Propiedad: | Función: |
|---|---|
| Tiles | The number of tiles the Texture is divided into in the X (horizontal) and Y (vertical) directions. |
| Animation | The Animation mode can be set to Whole Sheet or Single Row (that is, each row of the sheet represents a separate Animation sequence). |
| Random Row | Chooses a row from the sheet at random to produce the animation. This option is only available when Single Row is selected as the Animation mode. |
| Row | Selects a particular row from the sheet to produce the animation This option is only available when Single Row mode is selected and Random Row is disabled. |
| Frame Over Time | Una curva que especifica cómo el frame de la animación aumenta a medida que el tiempo progresa. |
| Start Frame | Allows you to specify which frame the particle animation should start on (useful for randomly phasing the animation on each particle). |
| Cycles | El número de veces que la secuencia de animación se repite sobre el tiempo de vida de la partícula. |
| Flip U | Horizontally mirror the Texture on a proportion of the particles. A higher value flips more particles. |
| Flip V | Vertically mirror the Texture on a proportion of the particles. A higher value flips more particles. |
| Enabled UV Channels | Le permite a usted especificar exactamente qué streams UV se afectan por el Particle System. |
Detalles
Las animaciones de la partícula son típicamente más simples y menos detalladas que las animaciones de los personajes. En sistemas dónde las partículas están visibles individualmente, las animaciones pueden ser utilizadas para transmitir acciones o movimientos. Por ejemplo, las llamas pueden parpadear y los insectos en una plagan podrían vibrar o estremecerse como si estuvieran batiendo sus alas. En casos dónde las partículas formen una sola, entidad continua como una nube, las partículas animadas pueden ayudar para agregarle una impresión de energía y movimiento.
You can use the Single Row mode to create separate animation sequences for particles and switch between animations from a script. This can be useful for creating variation or switching to a different animation after a collision. The Random Row option is highly effective as a way to break up conspicuous regularity in a particle system (for example, a group of flame objects that are all repeating the exact same flickering animation over and over again). This option can also be used with a single frame per row as a way to generate particles with random graphics. This can be used to break up regularity in a object like a cloud or to produce different types of debris or other objects from a single system. For example, a blunderbuss might fire out a cluster of nails, bolts, balls and other projectiles, or a car crash effect may result in springs, car paint, screws and other bits of metal being emitted.
UV flipping is a great way to add more visual variety to your effects without needing to author additional textures.
