To the left of the main key area is a field where you can add an external curve asset from the Content Browser to that track. For example, with all other keys set to Linear, and the center key set to Cubic-Auto, the track will look similar to the image below. Key interpolation only affects the curve between the key you interpolate for and the next key after that. Dragging horizontally will update the Time value of the key, while dragging vertically will update the Value.īy right-clicking a key, a drop down menu will appear for you to choose the interpolation type for that key. Multiple keys can be selected using the Ctrl key. To move a key along the timeline, select the key, then drag it. Selected keys can be deleted by pressing the Delete key on the keyboard. The time and value of the key can be set by clicking the key and entering the values into the time and value fields near the top of the track. Keys are added by holding the Shift key and clicking on the gray bar, or by right clicking on the gray bar and selecting the action Add Key To CurveFloat from the drop down menu.
In the editor, Create a new Actor Blueprint that contains a Timeline Component.ĭouble-click your timeline component to open the Timeline Editor.Ĭlick the Add Float Track button to add a CurveFloat to your Timeline Component. In this example, you will create a Curve Float that defines a curve of interpolated float points to evaluate over a given range. The data can be interpolated between these keys to calculate the value at any point during the Timeline.
Each track can have any number of keys that define a time and value. Curves can be vectors, floats, and colors. A Curve defines a track of interpolated points to evaluate over a given range.
