Game Dev Journey

We always want to target the enemy nearest to the home base

We will do this by comparing their progress and picking the enemy which has the highest value

However, we will limit the range the turrets can shoot and only allow them to target when they are within range

In the turret script:

Add an export variable for the range of the turret

Add a variable to represent the target

In the physics_process function

set the target to a function which picks the best target

if the target is valid

look at that target

In the timeout function

use the new target variable

create a new function to find the best target

note that this function returns a PathFollow3D (the target)

create local variables to store the:

best_target

best_progress

distance

Add a loop which repeats for each enemy in the list of enemies

if the current enemy has made the most progress

calculate the distance from the enemy to the turret

if the enemy is within range of the turret

set the best target to be the current enemy

set the best progress to current enemy progress

return the best target

Test the game again - you will see that the turrets attack the enemy nearest to the base if they are within range
