In Unreal Engine (Blueprints), repetition when setting variables from multiple execution paths is a very common issue. The best way to reduce this is to centralize your variable assignments into a single execution path instead of setting them multiple times.
Recommended approaches:
1. Use a single “Set Variables” point (merge execution paths)
-
Instead of setting variables inside each branch, route all execution paths into one final node.
-
Set all variables in one place.
-
This keeps logic cleaner and avoids duplication.
2. Create a Function or Macro
-
Put all variable-setting logic into a Function or Macro.
-
Call it from different paths.
-
This is the best solution if the same logic is reused often.
3. Use a Struct (advanced but clean)
-
Combine related variables into a Struct.
-
Pass the struct around and set it once.
-
Helps especially when you have many variables.
4. Use “Select” nodes before setting
-
Instead of branching multiple times, decide values using Select nodes.
-
Then feed results into a single Set node.
