How to instantiate object class that contains GameObject?

由 徘徊边缘 提交于 2019-12-12 04:45:25
问题 I am attempting to instantiate a large number of "particles" using a C# script in Unity. I have created a particle class that contains the creation of a corresponding GameObject. The GameObject within each particle instance is a sphere. When attempting to instantiate a new particle (Particle p = new Particle(...)) I get a Unity warning that the 'new' keyword should not be used. "You are trying to create a MonoBehaviour using the 'new' keyword. This is not allowed. MonoBehaviours can only be

Particles with different images. [qml]

由 北城以北 提交于 2019-12-12 03:59:59
问题 I am using particle systems . My particles come out from the center but I want different images to come out. The file path of these images are stored in an array. I made a function to go through that arrangement and return what is in each position. What returns is the path of each image to be sent to the source of the ImageParticle. The problem is that if you scroll through the entire array but only return the path of the last image and logically I get a single image instead of the twenty

Need help on speeding up a particle system (or how to ask turtles not to ask other turtles.)

问题 As a toy, it works well but obviously, when It scales up it bogs down. How can I do this system without asking turtles to ask the other turtles? the code is thus. to go ask turtles [ ask other turtles [ set heading towards myself let D distance myself let C .1 / D - 1 / (D ^ 2) if C > 1 [set C 1] fd C ] ] tick end I should know how to do this but the brain is not working. I will race y'all to the answer and post my own if I get it first. 回答1: You're doing essentially an N-body simulation. The

Performing Particle Analysis via ChooseMenuItem() - what is wrong

问题 This is a continuation of the question here. I am re-posting one of the answers to keep the topics cleaner. The original question (and continued question) is from user6406828. Trying to perform some (looped over) particle analysis, a couple of errors are thrown every now and then. What can be improved in this code? Here are some code: // $BACKGROUND$ number useBadImage, stopAtSrcImage // flags for test image histogram, src, stack taggroup imgLst number i, imgCt,imgID,x0,y0,x1,y1, z1 if

performance - drawing many 2d circles in opengl

由 故事扮演 提交于 2019-12-10 20:11:52
问题 I am trying to draw large numbers of 2d circles for my 2d games in opengl. They are all the same size and have the same texture. Many of the sprites overlap. What would be the fastest way to do this? an example of the kind of effect I'm making http://img805.imageshack.us/img805/6379/circles.png (It should be noted that the black edges are just due to the expanding explosion of circles. It was filled in a moment after this screen-shot was taken. At the moment I am using a pair of textured

Particles.js — modify on frame-change

由 我是研究僧i 提交于 2019-12-10 12:09:56
问题 Apologies for my complete lack of javascript intuition, but I was wondering if it is possible to change properties of a particles.js object dynamically: I'm using jQuery to detect when a user moves a slider on the screen (successfully). However, I was wondering how to apply these slider-value changes to the particles.js canvas I have in the background. I.e. Move the slider across, and the particles get larger. However, I'm not sure how to update the particles.js — is anyone familiar with a

Get started with animated typography/particles in javascript (mapping particles to a word)?

问题 Alright, so I have a good deal of experience with HTML and CSS, and some experience with Javascript (I can write basic functions and have coded in similar languages). I'm looking to start some visual projects and am specifically interested in getting into particle systems. I have an idea for something similar to Codecademy's name generator here (https://www.codecademy.com/courses/animate-your-name/0/1) where particles are mapped to a word and move if hovered over. It seems as though alphabet

问题 I've owned my Particle photon, for little over a week and after flashing my code it's breathing green and I can't flash anymore code to it. Why is this happening and how can I prevent it from occurring? 回答1: If you are getting a green breathing light or blinking red on your photon, try this!
