HOW IT WORKS:<\/h3>\n
A particle effect uses a lot of small animated pictures, called particles, to simulate visual phenomena. Once born, those particles move in the world for some time, then die.
You can create custom particle effects, like fire, sparks, or magical effects.
You can then use them for weapons effects, explosions, bullets, and item apparitions…
You can import your own texture, animated or not: just copy them in the Assets\\Particles directory.
(more on this there<\/a>)
The editor is divided into 3 sections, representing the life of a particle:
– Emitter<\/strong>:
The emitter acts as the source of particles. In this section, you can choose the emitter shape, size, and behavior, how many particles are spawned per second etc.
– Particle<\/strong>:
This section allows you to choose the look of each particle as well as its life duration.
– Modifiers<\/strong>:
Once the particle is born, it will live for some time, then die.
The modifiers change and animate the particle properties during its life:
For example, a particle is born white and with a 1 scale. Then, during its life, its color will be modified from white to red, and its scale from 1 to 10. Or a force will be applied to it, or it will rotate…<\/p>\n
PROPERTIES:<\/h5>\n
PARTICLE SYSTEM<\/strong><\/p>\n
This is where you can create, rename or delete your Particle system.
\"\" New Particle FX<\/strong> button: create a new Particle system.
 \"\" Delete Particle FX<\/strong> button: delete the selected Particle system.
\"\" Rename button<\/strong>: rename the selected Particle system.
\"\" Duplicate<\/strong> button: duplicate the selected Particle system.<\/p>\n
\n
PROPERTIES COLUMN<\/strong><\/p>\n
In this section, you can modify all your Particle system parameters: Emitter, particle, and modifiers.<\/p>\n
\"\" EMITTER TAB : Particle system settings:<\/strong><\/p>\n
\"\" max particles<\/strong> spinner: limits the maximum number of particles displayed at the same time for an emitter.
\"\" local space checkbox: if checked, the particles are “attached” to its emitter: if the emitter moves, the particles will follow the emitter. If unchecked, the particles are emitted in the world.<\/p>\n
EMITTER:<\/strong>
\"\" shape<\/strong> menu: the shape of the emitter.
There are 3 different shapes:
.point<\/strong>: the particles are emitted from a single point in space.
.box<\/strong>: the particles are emitted from the inside of a box.
.sphere<\/strong>: the particles are emitted from the inside of a sphere<\/p>\n
For box and sphere, you can modify the emitter shape dimensions:
\"\"\"\"\"\" size<\/strong> spinners: the x y z size of the emitter.<\/p>\n
\"\"infinite duration<\/strong> checkbox: if this is checked, the emitter will emit particles forever.
If the checkbox is unchecked, the emission duration is controlled manually:
\"\" emission duration<\/strong> spinner: the duration of the particle emission. After this duration, the emitter will stop emitting particles.
\"\" emission rate<\/strong> spinner: the number of particles emitted per second.<\/p>\n
OFFSET<\/strong>
\"\"\"\"\"\"x\/y\/z <\/strong>spinners: you can offset the emitter position from where it’s attached to.<\/p>\n
EMISSION DIRECTION
<\/strong>\"\"from the center: <\/b>forces particle’s velocity to come from the emitter position. Think of a ray starting from the emitter position and going to the particle birth position. Using negative velocities will move the particles from their birth position to the particle emitter position.<\/p>\n
\"\"<\/p>\n
<\/b>\"\"\"\"\"\"x\/y\/z <\/strong>spinners: the direction of the particle emission. A direction of 0,0,-1 will spawn particles going in front of the emitter. 1,0,0 will go to the right.
\"\" spread angle<\/strong> spinner: the angle deviation from the emitter direction: 10 will spawn particles in the direction of the emitter with a random angle from 0 to 10 degrees.
\"\"\"\"velocity min\/max<\/strong> range<\/strong> spinners: the velocity of the particle. It’s a random value between min and max. If you want all particles to have the same speed, set the same value for min and max.<\/p>\n
 \"\" PARTICLE TAB<\/strong><\/p>\n
\"\" texture<\/strong> menu: the texture used by the particles.
If the texture is from the Assets\/Particles directory, you have access to the texture animation settings:
\"\" columns<\/strong> spinner: Set the number of columns of the texture atlas
\"\" rows<\/strong> spinner: Set the number of rows of the texture atlas (see “animating sprites<\/a>” section for more information)<\/p>\n
\"\" random start frame<\/strong> checkbox: if checked, a random frame from the animated texture will be chosen. If the particle is animated, the animation will start from this frame. If not, this is a good way to add diversity to an emitter: you can create an atlas with 4 different debris pictures and the particles will choose randomly one of those pictures.
\"\" animation<\/strong> checkbox: if checked, the particle will animate its texture.
\"\" duration is particle life<\/strong> radio button: if checked, the animation duration is equal to the particle life, and so is played exactly once.
\"\" duration<\/strong> radio button: if this radio button is checked, the animation duration is using the duration value and will loop until the particle dies.
\"\" duration<\/strong> spinner: the animation duration.<\/p>\n
\"\" origin<\/strong> menu: you can choose the pivot position of the particles: it represents the center of the sprite and the origin (or pivot) used by the scale and rotations.
\"\" orientation<\/strong> menu:
. Sprite: the particle always fully faces the camera.
. Oriented_common: todo
. Oriented_self: the particles orients themselves to their velocity direction.
. Perpendicular_common: the particles are oriented in the camera direction. Good for rings, aureolas…
. Perpendicular_self: todo
\"\" size<\/strong> spinner: the size of the particle at its birth.
\"\" \"\" life min\/max<\/strong> range<\/strong> spinner: the particle life duration. That’s a random value between min and max.<\/p>\n
\"\" MODIFIERS TAB<\/strong><\/p>\n
The modifiers animate the particles during their life. They can animate the scale, color, rotation, or direction of the particles.<\/p>\n
SCALE<\/strong>
Modify the particle size during its life.
\"\" \"\"range start<\/strong> and end<\/strong> spinners: a random particle size. At the particle birth, the particle size is multiplied by a random number between the range start and end. (Example: a range of 0.5 and 2 will create particles with a size between half and twice the particle size)
\"\" rate<\/strong> spinner: the bigger the number, the faster the particle will change its scale. A negative number will shrink the particle.<\/p>\n
COLOR OVER LIFE<\/strong>
This controls the color of the particle: the particle’s color will go from the start color to the end color during its life. If you want the particle to keep the same color during its life, simply choose the same color for start and end.
\"\" start<\/strong> color: the color of the particle at its birth.
\"\" end<\/strong> color: the color of the particle at its death.<\/p>\n
ROTATION<\/strong>
This controls the particle rotation.
\"\" speed range start<\/strong> spinner: The start of a range of rotation speeds to be assigned to emitted particles.
\"\" speed range end<\/strong> spinner: The end of a range of rotation speeds to be assigned to emitted particles.
\"\" orientation range start<\/strong> spinner: The start of a range of rotation angles to be assigned to emitted particles.
\"\" orientation range end<\/strong> spinner: The end of a range of rotation angles to be assigned to emitted particles.<\/p>\n
FORCE<\/strong>
This controls the direction and strength of a force applied to all particles of this emitter. Like a wind, or gravity. The magnitude of this vector determines how strong the force is
\"\"\"\"\"\" x\/y\/z force<\/strong> spinners: ex: 0 0 100: a strong gravity effect<\/p>\n
DIRECTION RANDOMIZER<\/strong>
This adds randomness to the particle’s velocity direction.
\"\"randomness<\/strong> spinner: a bigger number will add more randomness.<\/p>\n
2D EFFECT<\/strong>
The moves of the particles are restricted to a plan.
\"\" enabled <\/strong>checkbox : enable or disable the modifier.<\/p>\n<\/div>","protected":false},"featured_media":0,"parent":138,"menu_order":10,"comment_status":"open","ping_status":"closed","template":"","doc_tag":[],"class_list":["post-1316","docs","type-docs","status-publish","hentry"],"_links":{"self":[{"href":"https:\/\/www.shmupcreator.com\/doc\/index.php?rest_route=\/wp\/v2\/docs\/1316","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.shmupcreator.com\/doc\/index.php?rest_route=\/wp\/v2\/docs"}],"about":[{"href":"https:\/\/www.shmupcreator.com\/doc\/index.php?rest_route=\/wp\/v2\/types\/docs"}],"replies":[{"embeddable":true,"href":"https:\/\/www.shmupcreator.com\/doc\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=1316"}],"version-history":[{"count":40,"href":"https:\/\/www.shmupcreator.com\/doc\/index.php?rest_route=\/wp\/v2\/docs\/1316\/revisions"}],"predecessor-version":[{"id":2981,"href":"https:\/\/www.shmupcreator.com\/doc\/index.php?rest_route=\/wp\/v2\/docs\/1316\/revisions\/2981"}],"up":[{"embeddable":true,"href":"https:\/\/www.shmupcreator.com\/doc\/index.php?rest_route=\/wp\/v2\/docs\/138"}],"prev":[{"title":"Explosion editor","link":"https:\/\/www.shmupcreator.com\/doc\/?docs=shmupcreator\/editors\/explosion-editor","href":"https:\/\/www.shmupcreator.com\/doc\/index.php?rest_route=\/wp\/v2\/docs\/142"}],"wp:attachment":[{"href":"https:\/\/www.shmupcreator.com\/doc\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=1316"}],"wp:term":[{"taxonomy":"doc_tag","embeddable":true,"href":"https:\/\/www.shmupcreator.com\/doc\/index.php?rest_route=%2Fwp%2Fv2%2Fdoc_tag&post=1316"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
