# Constant Rate
|
|
|
|
Menu Path : **Spawn > Constant Rate**
|
|
|
|
The Constant Rate Block adds a spawn count over time at a constant rate. For instance, if the rate is 10, this Block tiggers 10 spawn events per second for its Spawn Context. A rate below one is also valid, if the rate is 0.5, the rate is once every two seconds.
|
|
|
|
## Block compatibility
|
|
|
|
This Block is compatible with the following Contexts:
|

|
## Remarks
|
|
|
|
You can emulate this Block with the following equivalent custom spawner callback implementation:
|
|
|
|
```C#
|
|
|
|
class ConstantRateEquivalent : VFXSpawnerCallbacks
|
|
{
|
|
public class InputProperties
|
|
{
|
|
[Min(0), Tooltip("Sets the number of particles to spawn per second.")]
|
|
public float Rate = 10;
|
|
}
|
|
|
|
static private readonly int rateID = Shader.PropertyToID("Rate");
|
|
|
|
public sealed override void OnPlay(VFXSpawnerState state, VFXExpressionValues vfxValues, VisualEffect vfxComponent)
|
|
{
|
|
}
|
|
|
|
public sealed override void OnUpdate(VFXSpawnerState state, VFXExpressionValues vfxValues, VisualEffect vfxComponent)
|
|
{
|
|
if (state.playing)
|
|
{
|
|
float currentRate = vfxValues.GetFloat(rateID);
|
|
state.spawnCount += currentRate * state.deltaTime;
|
|
}
|
|
}
|
|
|
|
public sealed override void OnStop(VFXSpawnerState state, VFXExpressionValues vfxValues, VisualEffect vfxComponent)
|
|
{
|
|
}
|
|
}
|
|
```
