When a projectile is selected in the Levels Window, its properties may be edited using the Properties floating window (Command-0), as described below:
Projectile Name Field
Determines the name of the selected projectile
Projectile Type Pop-Up Menu
Determines the selected projectile's type. The Edit button may be used to edit the game project's projectile types, as described in the Projectile Creation section.
Location X and Y Fields
Determines the initial location of the selected projectile
Show/Hide Details Disclosure Triangle
Expands the Properties floating window, revealing controls for editing additional projectile properties
Current Horizontal Speed Field
Determines the initial horizontal speed of the selected projectile
Current Downward Speed Field
Determines the initial downward speed of the selected projectile
Current Propulsion Field
Determines the initial propulsion of the selected projectile. This value only applies to projectiles that have positive acceleration rates, like rockets. Bullets and other non-powered projectiles have no propulsion; their motion is determined exclusively by inertia and gravity.
Thrust Direction Field
Determines the direction in which the selected projectile faces; ranges from 0 to 360 degrees. 0 causes the projectile to point to the right; 90 causes it to point upwards; 180 causes it to point to the left; 270 causes it to point downwards. This property only affects projectiles with positive acceleration rates.
Target Character
If the selected projectile is guided, it will attempt to fly toward the character selected here.
Detonates Upon Hitting Player
Determines whether the selected projectile detonates upon hitting the player. This property only applies to projectile types that collide with characters.
Detonates Upon Hitting Characters
Determines whether the selected projectile detonates upon hitting enemy characters. This property only applies to projectile types that collide with characters.
