With this function you can check to see if a sequence element exists on the given layer. You supply the layer ID which can be a string of the layer name - as defined in the Room Editor - or the unique layer ID - as returned by the function layer_get_id(), as well the sequence element ID - as returned by layer_sequence_create() or by one of the layer element functions - and it will return true if the given element exists or false otherwise.
layer_sequence_exists(layer_id, sequence_element_id)
| Argument | Type | Description |
|---|---|---|
| layer_ID | String or Layer | The unique ID or name of the layer to check |
| sequence_element_id | Sequence Element ID | The unique ID value of the sequence element to target |
if (!layer_sequence_exists("Background", my_seq))
{
my_seq = layer_sequence_create("Background", 0, 0, seq_AnimatedBackground);
layer_sequence_pause(my_seq);
}
The above code checks to see if the given sequence element exists, and if it does not then it creates a new sequence on the given layer then pauses it.
