Description

Composite condition requiring all child conditions to pass.

SpawnConditionAll implements a logical AND over multiple SpawnCondition instances. The spawn is permitted only when every child condition returns `true` from `isSatisfied()`.

## Behavior

• Short-circuits on first failing condition
• Propagates `onCommit()` to all child conditions
• Accepts variadic condition arguments via constructor

## Usage

```cpp auto condition = std::make_unique<SpawnConditionAll>( std::make_unique<TimerCondition>(2.0f), std::make_unique<RequestedAmountIsAvailableCondition>(), std::make_unique<MaxActiveCondition>(10) );

// Spawns only when: timer elapsed AND pool available AND under max ```

SpawnConditionAll()

template <typename... Args>

helios::engine::runtime::spawn::policy::SpawnConditionAll::SpawnConditionAll (Args &&... args)

inline explicit

Constructs a composite condition from variadic arguments.

Template Parameters

Args	Types of spawn conditions (must be unique_ptr<SpawnCondition>).

Parameters

args	Spawn conditions to combine. Ownership transferred.

isSatisfied()

bool helios::engine::runtime::spawn::policy::SpawnConditionAll::isSatisfied (const size_t requestedAmount, const SpawnRuleState & spawnState, const helios::engine::runtime::pooling::GameObjectPoolSnapshot poolSnapshot, const helios::engine::runtime::world::UpdateContext & updateContext)

inline nodiscard noexcept virtual

Checks if all child conditions are satisfied.

Iterates through all conditions and returns `false` on the first condition that fails (short-circuit evaluation).

Parameters

requestedAmount	Number of entities requested for spawn.
spawnState	Current state of the spawn rule.
poolSnapshot	Snapshot of the entity pool.
updateContext	Current frame context.

Returns

`true` if all conditions pass, `false` otherwise.

onCommit()

void helios::engine::runtime::spawn::policy::SpawnConditionAll::onCommit (SpawnRuleState & spawnRuleState, const size_t spawnAmount)

inline virtual

Propagates commit to all child conditions.

Calls `onCommit()` on each child condition to allow them to update their internal state after a successful spawn.

Parameters

spawnRuleState	The rule's runtime state to update.
spawnAmount	The number of entities that were spawned.

124 }

onReset()

void helios::engine::runtime::spawn::policy::SpawnConditionAll::onReset (SpawnRuleState & spawnRuleState)

inline noexcept virtual

Propagates reset to all child conditions.

Parameters

spawnRuleState

The rule's runtime state to reset.
