As well as calculating this, there are many other formulae that calculate different things The formula(e) calculate(s) where on the screen the projectile should be. Anything that includes the curve of a projectile.In Scratch, the Trajectory formula is used for projects such as: One can also change the length of the sprite's costume so that it will still detect the intended targets.If the length of the sprite is less than 10 pixels, replace both 10's with at most the length of the sprite, or the sprite may pass through its intended targets.To make the projectile aim at the mouse pointer, place the following block after the 'go to x: () y: ()' block:.Switch costume to (player v) // makes sure the parent sprite looks like the player Switch costume to (bullet v) // makes the clone look like a projectile This method is more efficient because it only requires one sprite with two costumes: the player and the projectile. Wait (0.1) secs // change to amount of seconds between each shot When I start as a clone // in projectile spriteĪutomatic when gf clicked // in player sprite Semi-Automatic when gf clicked // in player spriteĬreate clone of (bullet v) // clones the projectile sprite Once again, both a player sprite and a projectile sprite are needed. This method is similar to the one above, only it incorporates cloning to allow for more than one bullet on the screen at once. Wait (0.1) secs // does not wait for the trigger to be released change to amount of seconds between each shot This script allows the player to simply hold the trigger button for continuous fire: Repeat until or > //moves the sprite until it is touching something that will make it go away Go to (The player v) //start at the player When I receive //in the projectile sprite Wait until or > // the player can only shoot once at a time When gf clicked // in the player's character sprite This script requires the player to release the trigger button before firing again.

These scripts require two sprites a player sprite and a projectile sprite. 5 Shooting Projectiles with Trajectories.
