# setMissionOptions

*Command · System · Arma 3 v2.18*

Locality: effect **local**

## Description

Sets various mission options. The options are automatically reset between missions and are saved/restored with the save system.

Available Options:

- IgnoreNoDamage: [Boolean](../topics/Boolean.md) - (default [false](../commands/false.md)) [true](../commands/true.md) to filter out no change in damage from [HandleDamage](../topics/Event_Handlers.md#handledamage) calls
- IgnoreFakeHeadHit: [Boolean](../topics/Boolean.md) - (default [false](../commands/false.md)) [true](../commands/true.md) to filter out FakeHeadHit context from [HandleDamage](../topics/Event_Handlers.md#handledamage) calls
- IgnoreUpsideDownDamage: [Boolean](../topics/Boolean.md) - (default [false](../commands/false.md)) [true](../commands/true.md) to ignore some minor upside down damage accumulation for a helicopter
- Arma 3 v2.20 SnakesCanOpenDoors: [Boolean](../topics/Boolean.md) - (default [false](../commands/false.md)) [true](../commands/true.md) to revert to legacy behaviour when snakes would open doors when entering houses
- Arma 3 v2.20 AIThinkOnlyLocal: [Boolean](../topics/Boolean.md) - (default [false](../commands/false.md)) [true](../commands/true.md) to disable processing targetting data for remote AI units, [knowsAbout](../commands/knowsAbout.md), [targets](../commands/targets.md) and similar commands will cease to work on remote units. For a gain in client performance because they no longer have to calculate all AI units.
- Arma 3 v2.24 MapSymbolIsHiddenWithTheObject: [Boolean](../topics/Boolean.md) - (default [true](../commands/true.md)) [true](../commands/true.md) to hide map symbol when terrain object is hidden.

- Arma 3 v2.24 MapHideRockFormations: [Boolean](../topics/Boolean.md) - (default [false](../commands/false.md)) [true](../commands/true.md) to hide map symbols for rock formations.
- Arma 3 v2.24 MapHideTowns: [Boolean](../topics/Boolean.md) - (default [false](../commands/false.md)) [true](../commands/true.md) to hide map symbols for towns.
- Arma 3 v2.24 MapHideRoads: [Boolean](../topics/Boolean.md) - (default [false](../commands/false.md)) [true](../commands/true.md) to hide map symbols for roads.
- Arma 3 v2.24 MapHideRivers: [Boolean](../topics/Boolean.md) - (default [false](../commands/false.md)) [true](../commands/true.md) to hide map symbols for rivers.
- Arma 3 v2.24 MapHideSigns: [Boolean](../topics/Boolean.md) - (default [false](../commands/false.md)) [true](../commands/true.md) to hide map icons for objects.
- Arma 3 v2.24 MapHideSmallSigns: [Boolean](../topics/Boolean.md) - (default [false](../commands/false.md)) [true](../commands/true.md) to hide map icons for trees, bushes, rocks.
- Arma 3 v2.24 MapHideLocations: [Boolean](../topics/Boolean.md) - (default [false](../commands/false.md)) [true](../commands/true.md) to hide map icons for trees, bushes, rocks.
