Game Dev Journey

Attach a script to the VericalFan node

We need access to the GPUParticles2D

and the AnimatedSprite2D

Create ready variables for these

create a variable for the upward force

create a variable for the player

Connect the

body entered signal

and the body exited signal

of the VerticalFan

Code the body entered function

so that if the body is in the player group

you assign the body to the player variable

you can turn the animation on or off at this point

and set the particles to emit

In our case since the on animation is set to autoplay

and the particles emitting property is on

lines 18 and 19 are not required.

Code the body exited function

so that if the player leaves the

fan area the player variable is

set to null so that no forces

can act on it anymore

Because the fan should repeatedly

push the player upwards

if the player is not null

call the push_up function

in the player script

In the Player script

Create the push_up function

It receives one parameter

the strength of the push

adjust the y velocity by that force
