Allows to set, into the client's decals array and at specific position index (0->511), a decal name.<br><br />
E.g: let's say you send a message to set a decal "{break" at index 200.<br><br />
As result, when a message TE_ will be used to show a decal at index 200, we will see "{break".<br />

This is the basic means of sending entity updates to the client.<br />
<br />
{{qnotice|''UpdateMask'' determines the frame which should be taken as a source for delta compression.}}<br><br />

{{qnotice|&nbsp;- from a "best" calculated baseline;}}<br><br />
{{qnotice|&nbsp;- from an instanced baseline set by the game library.}}<br><br />
{{qnotice|''NoDelta'' means there would be no delta information following the header.}}<br><br />
{{qnotice|Entity index can be short (6 bits) or long (11 bits). The short index is basically a difference between current and previous index.}}<br><br />

{{qnotice|Compression is done using one of three encoders: entity_state_t, entity_state_player_t and custom_entity_state_t.}}<br><br />
