Description
The Shoot behavior is an action behavior. When executed it will make your selected object shoot a projectile. This behavior contains predefined properties to make the creation of certain games easier. It's perfect for shooter games.
The Shoot behavior offers a lot of properties to customize the feel of your game. Try modifying the properties so your game doesn't feel like a generic shooter.
This behavior will Trigger an event once immediately when executed.
Properties
Triggers Immediately
| Object A |
This is the object that will be doing the shooting. By default the current object is selected, but you can tap the graphic to change it to any other object in your scene. Also note, that when selecting an object the blue target represents where the bullet will shoot from. You can move the blue target any where, and it will update the emitter location. |
| Sound |
You can select a sound effect to play when you shoot. |
| Bullet Graphic |
This is the graphic that represents the projectile you're shooting. Note that the size of the graphic is how big your bullet (and collision shape) will be. |
| Emitter Position |
This is the position where the projectile/bullet will shoot from. By default the bullet will shoot from the centre of the object. You can also use the Object B selector to visually change the emitter position by moving the blue target. |
| Initial Speed |
This is the speed that your bullet will shot at. Note, that if the "Physics" toggle is on, your bullet will slowdown due to other forces (gravity, air resistance etc.) The default value is 30 m/s. |
| Distance |
This is how far the bullet can reach before it no longer exists. The default value is 32 meters. |
| Shoot Angle |
This is the angle that the bullet is being shot from the object. ie. You can shoot from the front of the object instead of the top. The default value is 90 degrees. |
| Bullet Rotation |
This value sets the rotation of the graphic that represents your projectile. Change this value if your bullet is facing the wrong direction. The default value is 0 degrees. |
| Spray Range |
This is the spread of the bullets emitting from the object. If you have multiple bullets you can increase this angle to have them spread further apart. This is useful for creating a machine gun type weapon. The default value is 30 degrees.
|
| Spray Variance |
This value adds some randomness to the spread of the bullets (Spray Range). The higher the number, the more random your bullets appear to be. This is great for simulating recoil for a machine gun type weapon. The default value is 0%.
|
| # Bullets |
This is the amount of bullets that will emit when you press the shoot button. The default value is 1.
|
| Delay |
This is how long the gun will wait before emitting another bullet. This is useful if you want to slowdown the stream of projectiles and create a space between them. The default value is 0.5 seconds.
|
| Physics |
This toggle controls whether or not the bullets will conform to the physics engine. If this is on, gravity and other external forces will impact the speed and direction of your bullet. By default this toggle is off. |
| Destroy on Impact |
Toggle that controls whether or not the bullets die when they collide with other objects. If this toggle is off, and physics are off your bullets will bounce around the scene. By default this toggle is on. |
| # Alive Bullets |
This value controls how many bullets can be on screen at one time. Once you have shot this amount of bullets and they are still alive in the scene, you will not be able to shoot any more. |
| Play Animations |
When this toggle is on, your object will play an animation when the shoot button is pressed. You must select an animation from the Custom Animations panel. |
| Custom Animations |
On the left panel you can select an animation cycle to play when you press the shoot button. |
| Animation Priority |
On the left Custom Animations panel, you can prioritize your shoot animations so it does not conflict with another playing animation. The animation system will play a cycle with a higher priority. So if another animation behavior is interrupting your shoot animation, try increasing the priority. |
Outputs
| Object ID |
This outputs the Object ID. |
Examples
If you want to make a shooter game you can simply add this behavior to your player object, and it will automatically create a button on your Global UI layer, and make your character able to shoot. By modifying the properties you can create a wide range of weapons from pistols, machine guns, rocket launchers, or other projectile based weapons.
