Struct CustomRuleBuilder 

pub struct CustomRuleBuilder { /* private fields */ }

Builder for creating custom rules with dynamic parameters.

Use Rule::custom_dynamic or Rule::neighbor_custom_dynamic to create.

Implementations

impl CustomRuleBuilder

pub fn with_param<V: Into<UniformValue>>(self, name: &str, value: V) -> Self

Add a parameter that can be edited at runtime.

The parameter will be accessible in WGSL as uniforms.rule_N_name where N is the rule index.

Supported Types

• f32 - Single float
• u32, i32 - Integers
• Vec2, Vec3, Vec4 - Vectors

Example

Rule::custom_dynamic("p.velocity.y += uniforms.strength;")
    .with_param("strength", 2.0)

pub fn with_radius(self, radius: f32) -> Self

Set the collision radius (only for collision rules).

pub fn build(self) -> Rule

Build the rule. Usually not needed as the builder converts automatically.
