Unreal Game Engine – Blueprints – Mesh Rotator

1. LEFT COLUMN> Content Browser> RMB over a Mesh (example Floor_400x400)> Create Blueprint Using…> select your ‘Blueprints’ folder> give it the name (example Floor_400x400_Blueprint)

2. Blueprint window> TOP RIGHT> Components> WHELL MOUSE BUTTON to zoom in/out

3. Blueprint window> TOP RIGHT> Graph> you can see component on the RIGHT COLUMN: – StaticMesh1

4. Blueprint window> TOP RIGHT> Graph> RMB over an Empty Area> Add Timeline

5. DOUBLE CLICK Timeline box> Timeline window> Add Vector Track

6. Vector Track> TOP LEFT> name the track ‘Rotator’

7. Vector Track> TOP> Length> 1 second

8. Vector Track> RMB over empty area> Add Key: 0 sec->1 / 1 sec->360

9. Float Track> TOP> check Autoplay and Loop

10. Event Graph> RIGHT COLUMN> DRAG AND DROP StaticMesh1 over an empty area> Get (to add StaticMesh1 block)

11. Event Graph> DRAG from StaticMesh1 to an empty area> Set Relative Rotation (to add Relative Rotation block)

12. Event Graph> DRAG from Timeline>Update to Set Relative Rotation>exec

13. Event Graph> DRAG from Timeline>Rotator to an empty area (to add Break Vector)

14. Event Graph> DRAG from Set Relative Rotation>New Rotation to an empty area (to add Make Rot block)

15. Event Graph> Create other connections as in the image below

16. Unreal Editor> Content Browser> Blueprint folder> ‘Floor_400x400_Blueprint’ DRAG AND DROP into scene

17. Play

For italian people: come funziona?

1. Timeline invia i valori di Rotator ad ogni fotogramma alla funzione Set Relative Rotation
2. Set Relative Rotation invia i dati di rotazione a Static Mesh 1

NOTA BENE: la traccia Rotator deve essere prima separata con Break Vector, poi assegnata con Make Rot a New Rotation

Unreal Game Engine – Blueprints – Pulsing Mesh

1. LEFT COLUMN> Content Browser> RMB over a Mesh (example Floor_400x400)> Create Blueprint Using…> select your ‘Blueprints’ folder> give it the name (example Floor_400x400_Blueprint)

2. Blueprint window> TOP RIGHT> Components> WHELL MOUSE BUTTON to zoom in/out

4. Blueprint window> TOP RIGHT> Graph> you can see component on the RIGHT COLUMN: – StaticMesh1

5. Blueprint window> TOP RIGHT> Graph> RMB over an Empty Area> Add Timeline

6. DOUBLE CLICK Timeline box> Timeline window> Add Float Track

7. Float Track> TOP LEFT> name the track ‘Pulsing’

8. Float Track> TOP> Length> 1 second

9. Float Track> RMB over empty area> Add Key: 0 sec->1 / 0.5 sec->0.5 / 1->1

10. Float Track> TOP> check Autoplay and Loop

11. Event Graph> RIGHT COLUMN> DRAG AND DROP StaticMesh1 over an empty area> Get (to add StaticMesh1 block)

12. Event Graph> DRAG from StaticMesh1 to an empty area> Set Relative Scale 3D (to add Relative Scale 3D block)

13. Event Graph> DRAG from Timeline>Update to Set Relative Scale 3D>exec

14. Event Graph> DRAG from Timeline>Pulsing to Set Relative Scale 3D>New Scale

14. Unreal Editor> Content Browser> Blueprint folder> ‘Floor_400x400_Blueprint’ DRAG AND DROP into scene

15. Play

For italian people: come funziona?

1. Timeline>Update —> Set Relative Scale 3D: esegue un update continuo di Set Relative Scale 3D ad ogni fotogramma

2. Timeline>Pulsing —> New Scale: fornisce il valore variabile nel tempo

3. Set Relative Scale 3D>Target —> Static Mesh 1: setta la scala di Static Mesh 1

Unreal Game Engine – BluePrints – Variables and Datatypes

1. LEFT COLUMN> Content Browser> New> Blueprint> Actor> name it ‘MyBlueprint’, double click to open it.

2. MyBlueprint window> LEFT COLUMN> +Variable, nami it ‘MyFirstVar’

3. MyBlueprint window> LEFT COLUMN> Details> Variable Type> select the type between:

– bool : boolean
– byte
– int : integer numbers
– float : floating point numbers
– name
– string : alphanumeric characters
– text
– Vector : XYZ
– Rotator : rotation information
– Transform: translation, rotation, scale

+————-| on the right click over the red ‘Array’ icon to create an array.

4. DRAG AND DROP ‘MyFirstVar’ into EventGraph> Get> now the Variable Type is permanent and it can’t be changed.
