{{newin|[[11.0]]|110||type=function|text=It has been renamed from [[ParticleSystem:setAreaSpread]]}}
Sets area-based spawn parameters for the particles. Newly created particles will spawn in an area around the emitter based on the parameters to this function.
== Function ==
=== Synopsis ===
<source lang="lua">
ParticleSystem:setEmissionArea( distribution, dx, dy, angle, directionRelativeToCenter )
</source>
=== Arguments ===
{{param|AreaSpreadDistribution|distribution|The type of distribution for new particles.}}
{{param|number|dx|The maximum spawn distance from the emitter along the x-axis for uniform distribution, or the standard deviation along the x-axis for normal distribution.}}
{{param|number|dy|The maximum spawn distance from the emitter along the y-axis for uniform distribution, or the standard deviation along the y-axis for normal distribution.}}
{{param|number|angle (0)|The angle in radians of the emission area.}}
{{param|boolean|directionRelativeToCenter (false)|True if newly spawned particles will be oriented relative to the center of the emission area, false otherwise.}}
=== Returns ===
Nothing.
