Benefits of technology

The technical effect of this new technology compared to previous methods lies within its ability to improve efficiency or reduce costs by making it more efficient than existing technologies while also improving quality control measures for manufacturing processes.

Problems solved by technology

This patented describes how it can be used with different types of applications or tools like Java code. However, this approach has limitations due to its serial playing back process where each iteration requires an entire screen image before being able to see what changes have happened during previous steps.

Embodiment Construction

[0057] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0058] refer to figure 1 , which shows a flow chart of a method for realizing particle effects in the present invention, and this embodiment may specifically include the following steps:

[0059] Step 101, acquire the number of frames needed to realize the particle effect, and record it as the number of frames of the current frame.

[0060] For example, it is the fifth frame that needs to realize the particle effect, and the frame number is 5, then the frame number of the current frame is also recorded as 5, that is, the current frame is recorded as the fifth frame.

[0061] Step 102, create an update function of the particle system and an update function of the influencer.

[0062] This embodiment extends the third-party SDK, a...

Abstract

The invention provides an implementation method and device of particle effects and solves the problem that the larger the number of current frames, the longer time implementation of current frame particle effects takes. The method includes: collecting the number of frames requiring particle effects, and recording as the number of current frames; establishing an update function of a particle system and an update function of an affector; calling a clear function of the particle system, and removing all particles of the particle system; setting emission speed and maximum survival time of the particle system; calling the update function of the particle system to create current frame particles, and modifying the emission speed, maximum survival time and locations of the current frame particles; calling the update function of the affector, and updating parameters of the current frame particles; calling a render function to render the parameters of the current frame particles so that particle effects of the current frame particles are implemented. The method and device has the advantages that the time of implementing the effects of current particles is saved.
