With this function you supply the sequence element ID - as returned by layer_sequence_create or by one of the layer element functions - and it will return the current playhead direction, which will be one of the constants listed below.
| Constant | Description | Value |
|---|---|---|
| seqdir_right | The sequence will play frames in an incremental order from left to right | 1 |
| seqdir_left | The sequence will play frames in a decremental order from right to left | -1 |
layer_sequence_get_headdir(sequence_element_id)
| Argument | Type | Description |
|---|---|---|
| sequence_element_id | Sequence Element ID | The unique ID value of the sequence element to target |
if layer_sequence_get_headdir(title_sequence) != seqdir_left
{
layer_sequence_headdir(title_sequence, seqdir_left);
}
The above code checks the current playhead direction of the sequence element ID stored in the variable title_sequence, and if it's not set to seqdir_left, it is set to this value.
