所以我一直试图弄清楚如何在Corona SDK中使用粒子系统。 我已经尝试了阅读它,我已经到了发射器,但是从那里被卡住了。如何将粒子系统和发射器连接在一起?
function NewTrail()
ParticleSystem:createParticle(
{
flags = { "wall" },
x = display.contentCenterX,
y = display.contentCenterY,
velocityX = 100,
velocityY = 0,
color = { 0, 0, 1, 1 },
lifetime = 32.0
}
)
end
timer.performWithDelay( 100, NewTrail, -1 )
-----------------------emitter---------------------------
local emitterParams = {
textureFileName = "particle.png",
}
local emitter = display.newEmitter( emitterParams )
好的,所以在这之后没用,我想也许粒子系统和发射器是两个不同的东西所以我试过这个:
local emitterParams = {
textureFileName = "images/particle.png",
duration = -1,
speed = 100,
particleLifespan = 5,
maxParticles = 20,
angle = 180,
startParticleSize = 10,
finishParticleSize = 0,
}
local Trail = display.newEmitter( emitterParams )
Trail:start()
它仍然无效。有什么输入吗?
答案 0 :(得分:0)
好的,我终于明白了。我仍然不了解发射器,所以如果有人愿意帮助你,请做。要使粒子系统工作,您必须首先启动物理学:
local physics = require( "physics" )
physics.start()
然后通过执行以下操作初始化粒子系统:
local testParticleSystem = physics.newParticleSystem(
{
filename = "images/particle.png",
radius = 3,
imageRadius = 4
}
)
最后,您必须创建实际粒子,如下所示:
local function onTimer( event )
testParticleSystem:createParticle(
{
flags = "water",
velocityX = 256,
velocityY = 480,
color = { 1, 0, 0.1, 1 },
x = 0,
y = 0,
lifetime = 32.0
}
)
end
timer.performWithDelay( 20, onTimer, 0 )
