1. ❓ Why Does My GAS Ability Get Called Multiple Times Before EndAbility
?
🎉Solution:
🚀 Problem:
Your GA_Hello
ability is being triggered multiple times before it ends, leading to unexpected behavior. For example, logs show repeated activations like GA_Hello_C_0
, GA_Hello_C_1
, etc., even though the previous instance hasn’t finished.
🔧 Solution:
The issue is likely due to the Instancing Policy of your ability. By default, if the policy is set to InstancedPerActor
, a new instance of the ability is created every time you activate it, even if the previous instance hasn’t ended. This causes the ability to stack and trigger repeatedly.
Here’s how to fix it:
- Open your ability blueprint:
GA_Hello
🖼️ - Go to Class Defaults ⚙️
- Find the Instancing Policy setting 📜
- Change it from
InstancedPerActor
toInstancedPerExecution
✅
💡 Why this works:
InstancedPerActor
creates a new instance for each actor every time the ability is activated, even if the previous instance is still active.InstancedPerExecution
ensures only one instance of the ability exists per activation, preventing multiple triggers until the ability ends withEndAbility
.
🎉 Result:
Your ability will now only activate once until it properly ends, giving you more control over its behavior!
