Gymbyl Coding
#1

Hi,

for previous versions of CBEffects there were some very interesting examples included in CBResources repository on GitHub: https://github.com/Poordeveloper/corona_code/tree/master/Game.

Unfortunately they are not compatible with the latest version of CBEffects (I’m using 3.1 version).

I tried to convert some code but I have some problem with properties velX and velY:

onCreation=function(particle) particle.velX = particle.velX+(math.random(-10, 10)/25); particle.velY = particle.velY+(math.random(-10, 10)/25) -- Give a bit of random jitter end

It seems that these properties are no longer present…

Is there a way to convert older examples, contained in the file “Samples” folder, to the new versions of CBEffects?

Thanks in advance.

Regards.

Alas, there is no easy way to do that. You can apply force to the particle with particle:applyParticleForce(), so you could use that for randomization.

Thanks a lot! Caleb

With your suggestions something begins to work…

Sorry, but with this beautiful library I’m still a beginner. 

Compared to the original example “Vector Mini Fireworks”, I do not see the explosions green circles and, after the first, it seems there are more contemporary “mortar” instances. 

What is wrong?

local CBE = require("CBEffects.Library") sampleVGroup=CBE.VentGroup{ { preset="sparks", title="explosion", -- The explosion vent color={{0, 255, 0}}, build=function() return display.newCircle(0, 0, 3) end, onCreation=function(particle) --particle.velX=particle.velX+(math.random(-10, 10)/25); particle.velY=particle.velY+(math.random(-10, 10)/25) -- Give a bit of random jitter particle:applyParticleForce(math.random(-10, 10)/25, math.random(-10, 10)/25 ) end, perEmit=6, positionType="atPoint", onDeath=function()end, physics={ relativeToSize=false, velocity=2, gravityY=0.05, -- Just a slight bit of gravity downwards iterateAngle=true, -- We want to go perfectly through the angles autoAngle=false, angles={ 0, 60, 120, 180, 240, 300 } } }, { preset="sparks", title="pop", -- The pop that appears when a mortar shot explodes build=function() return display.newCircle(0, 0, 10) end, color={{0, 255, 0}}, positionType="atPoint", perEmit=1, lifeSpan=300, fadeInTime=0, alpha=1, onDeath=function()end, physics={ sizeX=0.2, -- Grow X and Y sizeY=0.2, relativeToSize=false, velocity=0, gravityY=0 } }, { preset="sparks", title="mortar", -- Mortar vent color={{0, 255, 0}}, build=function() return display.newCircle(0, 0, 4) end, onDeath=function(particle, vent) sampleVGroup:translate("explosion", particle.x, particle.y) sampleVGroup:emit("explosion") -- Move and fire off the explosion sampleVGroup:translate("pop", particle.x, particle.y) sampleVGroup:emit("pop") -- And the pop end, x=512, y=668, emitDelay=500, fadeInTime=100, lifeSpan=100, lifeStart=500, positionType="atPoint", perEmit=1, physics={ angles={{60, 120}}, relativeToSize=false, velocity=15, gravityY=0.2 } } } sampleVGroup:start("mortar")

Many, many thanks!

Cheers
