| |

| * [[Object]], [[Group]] or [[netId]] - The persistent execution of the [[remoteExecCall]] statement is attached to the given object or group.<br>When the object / group is deleted, the [[remoteExecCall]] statement is automatically removed from the JIP queue.
| |

| "Example 1" [[remoteExecCall]] ["hint", 3]; {{cc|Executed only on the first connected client.}}

| "Example 1" [[remoteExecCall]] ["hint", -2]; {{cc|Executed everywhere except on the server.}}</code>
| |
| | |
| |x2= Execute {{ic|[[hint]] "Example 2";}} on various machines and add it to the JIP queue:
| |
| <code>_result = "Example 2" [[remoteExecCall]] ["hint", -2, [[true]]]; {{cc|_result is a unique JIP ID, e.g. "3_1".}}
| |
| _result = "Example 2" [[remoteExecCall]] ["hint", -2, "My_JIP_ID"]; {{cc|_result is "My_JIP_ID".}}
| |
| _result = "Example 2" [[remoteExecCall]] ["hint", 0, MyObject]; {{cc|_result is the unique [[netId]] of MyObject, e.g. "2:3".}}</code>
| |
| Note that if there already was a statement with the JIP ID "My_JIP_ID" in the JIP queue, that statement has now been overwritten.

| Remove statements from the JIP queue:
| |
| <code>[[remoteExecCall]] ["", "My_JIP_ID"]; {{cc|The persistent statement with the JIP ID "My_JIP_ID" is removed from the JIP queue.}}
| |
| [[remoteExecCall]] ["", MyObject]; {{cc|The persistent statement attached to MyObject is removed from the JIP queue.}}</code>
| |
| | |
| |x4= Some more complex examples:
| |
| <code>["Open", [[true]]] [[remoteExecCall]] ["BIS_fnc_arsenal", MyTargetPlayer];
| |
| [MyCurator, [[MyObject1, MyObject2], [[false]]]] [[remoteExecCall]] ["addCuratorEditableObjects", 2];</code>
| |
| | |
| |x5= A tricky example: Trying to execute {{ic|[[player]] [[setAmmo]] [<nowiki/>[[primaryWeapon]] [[player]], 1];}} (on machines where the player is in MyGroup). Consider the following statements:
| |
| <code>{[[player]] [[setAmmo]] [<nowiki/>[[primaryWeapon]] [[player]], 1];} [[remoteExecCall]] ["call", MyGroup]; {{cc|Statement 1}}
| |
| <nowiki>[</nowiki>[[player]], [<nowiki/>[[primaryWeapon]] [[player]], 1]] [[remoteExecCall]] ["setAmmo", MyGroup]; {{cc|Statement 2}}</code>
| |
| Both statements look very similar, but only Statement 1 has the intended effect. This is because in Statement 2, the arguments {{ic|[[player]]}} and {{ic|[[primaryWeapon]] [[player]]}} are not resolved on the target machine(s), but on the machine executing [[remoteExecCall]].
