With this function you can compress part (or all) of a buffer using zlib compression. You supply the ID of the buffer to compress (as returned by buffer_create()), the offset within the buffer to use in bytes, and the size of the buffer data to compress (also in bytes). The function will return a new buffer ID value for the compressed buffer, or a value less than 0 if it has failed for any reason. This function will not alter the original buffer.
buffer_compress(buffer, offset, size);
| Argument | Description |
|---|---|
| buffer | The index of the buffer to compress. |
| offset | The offset within the buffer to compress (in bytes). |
| size | The size of the buffer area to compress (in bytes). |
Int (Buffer ID value)
var srcBuff = buffer_create(1024, buffer_grow,
1);
buffer_write(srcBuff, global.DataString);
var cmpBuff = buffer_compress(srcBuff, 0,
buffer_tell(srcBuff));
buffer_save(cmpBuff, "Player_Save.sav");
buffer_delete(srcBuff);
buffer_delete(cmpBuff);
The above code will create a buffer then populate it with the data from a string. This buffer is then compressed and saved, and both the source and compressed buffers are deleted
