Free fly experience
Cloud Painting - Gathering and release clouds
Cloud Fight �C Transition between different cloud types
Create Weather - Thunder Head
Puff: One cloud particle in the simulation
Cloud: One or a group of Puffs sticking together as a whole
Cloud Power: Each Puff from the same Cloud contains a number which represents its power and visually indicated by transparency and brightness
Dark Puff:
Puff that has negative power is regarded as Dark Puff, and visually
seen as grey and black, the darker it looks the bigger its negative power could
be.
Cloud
Owner: Each cloud Puff has an owner.
It can be cloud boy or neutral.
Layer: Cloud
can exist in multiple altitudes. But one specific cloud can not stay in other
altitude. So we divide cloud into different Layers by their altitude. Puff
can only interact with other Puffs from the same Layer.
Cloud Attraction Rule: Every Puff in the
game has potential to attract each other when they are close in the effective
range. A Puff can attract equal or less powerful Puff, but not
the more powerful one. When it comes to Dark Puff, the system will treat
it as if its power is positive.
Cloud Collide Rule: When two Puffs collide, they will change their owners and transfer power little by little till it's evenly spread. For example, 90 + 30 => 60 + 60.
Cloud Owner Rule: As soon as two Puffs
collide, depending on their power, both Puffs will belong to the
stronger one's owner. The Dark Puffs never belong to cloud boy.
Cloud Fight Rule: Cloud fight starts when a
normal Puff collides with a Dark Puff. Due to the Dark Puff's
negative value, they will consume each other. The power that is consumed will
turns into Rain and Lightening.
For example 30 + -100 => -35 + -35, the consumed 60 will translate into
equal amount of Rain. When the
consumed power is very high it triggers Lightening
Cloud Consume: Cloud boy can perform an action that sucks all the clouds he's dragging and consume them into his own power
Cloud Release: Opposite effect of Cloud Consume, cloud boy will release his power and form cloud. He can not only create powerful puff by releasing all his power onto one, but also a nice trail of less powerful puffs by releasing and moving.
Cloud Drag: Similar to what we have currently, cloud boy can drag his clouds to pick up more clouds.
Day Dream 1
Intro: Intro animation based on storyboard
Exposition: Yun flies for his first time
Map: There are very limited clouds with low power on layer 1 and one powerful cloud puff for player to pick up.
Goal 1: Find
and capture a Powerful Cloud
Learning 1: 360 flying control + camera control
Goal 2: Use the newly captured cloud to collect the rest clouds and create a big cloud
Learning 1: Cloud Drag control + camera control
Learning 2: Understand Cloud Attraction Rule, Cloud Collide Rule
Dialog / Instructions
"Find
the cloud that belongs to you"
"Space
Bar Symbol" appears at bottom of the screen
When cloud boy gets close to the purified cloud, "LMB Symbol"
"Guide
it and make it bigger"
After cloud boy collects half of the cloud,
"Isn't this fun? Let's do more"
Nearly collected all the cloud, "Wow, that is a
big cloud"
After collected all the cloud, "That has been
fun, but you need to go back"
Day Dream 2
Intro: Yun plays chess with the mysterious girl at hospital
Exposition: Yun needs to create a checker pattern (indicated by ghost) on the sky
Map: There are two layers of clouds with high power
Goal 1: Fill
in at least half of the checkers
Learning 1: Cloud Consume, Cloud Release control
Learning 2: How to use Cloud Consume, Cloud Release to create a
powerful Puff
Learning 3: Understand Cloud Owner Rule
Goal 2: Bring clouds from layer 2 to layer 1 to finish the rest checkers
Learning 1: Understand clouds in different layers can not be dragged vertically but possible to transferred by consuming them into power
Learning 2: How to use Cloud Consume, Cloud Release to create large but less powerful cloud
Dialog / Instructions
"Let's
make a TBD on the sky"
"TBD
shape's silhouette" appears on the map
When cloud boy lost clouds to the more powerful clouds, "Be
careful"
"Those
clouds are stronger than yours"
If cloud boy still has clouds or if he has picked up a new
cloud, "Your clouds can be stronger. First gather them up"
"Consume
Symbol" shows at the bottom of the screen
After consume, "Now release them and make a
stronger one"
"Release
Symbol" shows at the bottom of the screen
If none of the clouds at the higher layer are moved down
and all the clouds at the bottom layer have been moved into the target area,
"There are more clouds above"
"Gather
them up and bring them back"
After fills up the target area, "How beautiful!"
Day Dream 3
Intro: A hot summer afternoon, a heavy industrial cityscape, dark clouds appear
Exposition: Dark clouds keep spawning from the city island and move towards Yun's island. Yun has to stop them before they reach the island.
Map: There are three layers of clouds on the sky with different size and powers. On top of the city island, there will be a dark cloud generator which spits out dark clouds moving to Yun's island. As time passes, the dark cloud will become stronger and stronger and appear in multiple layers.
Goal 1: Stop Dark Clouds
Learning 1: Understand Cloud Fight Rule, Rain,
Lightning
Learning 2: Become comfortable to manipulate clouds in different layers
Dialog / Instructions
When dark clouds come from multiple layers "There
are more coming above"
"I like sleeping in on a rainy day, don't you?" with rain SFX?
Day Dream 4
Intro: Polluted city, building, plants, irrigating flowers with spray
Exposition: Create a huge storm to wash the polluted city. A huge storm is literally a cloud pyramid formed by clouds on multiple layers (area indicated by ghost)
Map: Five to seven layers of clouds, occasionally spawns some dark clouds
Goal 1: Create a storm
Learning 1: How to create a Storm
Learning 2: Storm
generates Rain, Lightening
Goal 2: Drag and grow the Storm to clean up the rest area
Learning 1: Once the Storm is formed, cloud boy can drag the entire Storm from the top layer, and the rest part in other layer will move together.
Dialog / Instructions
The ghost of the thunderhead appears in multiple layers
When one of the layers is filled with clouds "Let's
make it really big"
When the storm is complete, the ghost disappears. It starts
raining."This is going to be a nice storm."
After it rains for a while "Now bring the rain to the city"
"Look it's a rainbow"
Rain
Lightening
Storm
