[ ](/ab_p/beta/docs/entityprojectile.md){: .abp .tooltip .badge }

#### void AddProjectileFlags ( int Flags ) {: .copyable aria-label='Functions' }

Uses [ProjectileFlags](https://github.com/wofsauge/IsaacDocs/tree/420a6aaa54ea230461fb26e61297c068492684de/beta/enums/ProjectileFlags/README.md) to define the projectile attributes.

## Variables

### Acceleration {: aria-label='Variables' }

[ ](/ab_p/beta/docs/entityprojectile.md){: .abp .tooltip .badge }

#### float Acceleration  {: .copyable aria-label='Variables' }

### ChangeFlags {: aria-label='Variables' }

[ ](/ab_p/beta/docs/entityprojectile.md){: .abp .tooltip .badge }

#### int ChangeFlags  {: .copyable aria-label='Variables' }

Uses [ProjectileFlags](https://github.com/wofsauge/IsaacDocs/tree/420a6aaa54ea230461fb26e61297c068492684de/beta/enums/ProjectileFlags/README.md) to define the projectile attributes after the "Changed" state was activated. The [ProjectileFlag](https://github.com/wofsauge/IsaacDocs/tree/420a6aaa54ea230461fb26e61297c068492684de/beta/enums/ProjectileFlags/README.md).CHANGE\_FLAGS\_AFTER\_TIMEOUT needs to be set to allow for this change to apply!

**Informations about "Changed" State:**

Projectiles can have two states: normal (default) and changed.

Changed state activates when projectile's frame count reaches the value set in [ChangeTimeout](/ab_p/beta/docs/entityprojectile.md#ChangeTimeout). After that its flags get changed to what was set in [ChangeFlags](/ab_p/beta/docs/entityprojectile.md#ChangeFlags) and velocity will be resized to length set in [ChangeVelocity](/ab_p/beta/docs/entityprojectile.md#ChangeVelocity).

Also used in: [ProjectileParams()](https://github.com/wofsauge/IsaacDocs/tree/420a6aaa54ea230461fb26e61297c068492684de/beta/ProjectileParams/README.md)

### ChangeTimeout {: aria-label='Variables' }

[ ](/ab_p/beta/docs/entityprojectile.md){: .abp .tooltip .badge }

#### int ChangeTimeout  {: .copyable aria-label='Variables' }

Number of frames that need to elapse after spawn till the "Changed" state is activated. The [ProjectileFlags](https://github.com/wofsauge/IsaacDocs/tree/420a6aaa54ea230461fb26e61297c068492684de/beta/enums/ProjectileFlags/README.md).CHANGE\_FLAGS\_AFTER\_TIMEOUT or CHANGE\_VELOCITY\_AFTER\_TIMEOUT need to be set to allow for this change to apply!

Changed state activates when projectile's frame count reaches the value set in [ChangeTimeout](/ab_p/beta/docs/entityprojectile.md#ChangeTimeout).
