Unity3d playmaker Plug-in tutorial, six, blood volume display and processing

This shows how to handle and display the amount of blood, how to use global variables to pass information under multiple state machines, how to use a similar if judgment, and how to convert data types.

Prepare work, blood volume display text box

Bloody props.

Simulate player's bucket

First, create a new empty game Object, named Healthmanager, to manage the entire process

Add Setup, Updategui, addhealth, listener status.
Add the Add_health event.

Add Global variables

If you add a global variable, you cannot add and the following error occurs

Because a directory is missing, you can add a resources directory under the Assets\plugins\playmaker directory.

Add 3 global Variables

Add current_health_i storage volume, type integer

Add current_health_s to display the amount of blood, type string

Add Health_manager for delivery, type is Gameobject

Add state rotate under Health_cross, add rotate action to rotate the cross

Add a cube that determines the range.

Yesterday saw the next playmaker website, said, there is a unified father's words can be convenient to get all the son. It seems to be the meaning. Just do it.

Add the setup state and the Updatehealth state to the cube and add the Health_pick_up event. and add the trigger event action in the Setup state

Add the Get Parent action and Destory object action in the Updatehealth state, destroying itself when the player touches it.

This is to send the player a message to Healthmanager and add the Send event action

This time, the global variable Health_manager is working, set the following

At this point, you also need to set the Add_health event under Healthmanager as a global event,

Then fill in the state machine name and check the global event add_health.

The global variable Health_manager has not yet been assigned, and in the Healthmanager setup state, add the get owner action,

Run preview, when the player touches the booster, the Healthmanager state is triggered correctly.

In the setup state of Healthmanager, add action: Set Int Value, set the blood volume to 50,

In the Updategui state, add the convert Int to string action, transform the data type, and add the set GUI text action to display the amount of blood.

Add the action int add in the Addhealth state to modify the amount of blood.

Run preview, start status

Contact with the booster, state trigger, blood volume display correct

Add a blood-reducing platform, it is a fire, the monster put the trap of what is good.

Add Listener, decreasehealth status,

Add Decrease_health Event

Add trigger event action in listener state to handle incoming

As with the addition of blood, you need to add decrease_health global events under Healthmanager.

Add the Send event action on the Cube fire side,

Run preview

When entering cube, the state is triggered correctly.

This time, when the player constantly pick up the blood booster, the amount of blood will always increase, the blood volume is less than 0 can also continue.

Now to deal with this problem.

Due to the limitations of playmaker plug-in judgment function, the idea is as follows.
After adding blood or reducing blood, go to CheckHealth100 State
In this state to detect whether the blood volume is more than 100,
If more than 100, change the amount of blood in the resethealth state back to 100
If not more than 100, go to CheckHealth0 state, determine whether the blood volume is less than or equal to 100
When the amount of blood is less than or equal to 0 o'clock, the game ends.

Add an int compare action in the CHECKHEALTH100 state, the first value is the amount of blood, the second value is 100,

Equal, less than, more than triggering different actions respectively.

Feel this paragraph, write code to come simple.

When the blood volume exceeds 100, the amount of blood is changed back to 100 with the set INT value action.

When the amount of blood is less than or equal to 0, the game is over

When the game is over, simply display the text.

Run a preview when the player's blood volume is 100

And then we'll have the blood and the blood.

When the player's blood volume is less than 0, the game over is displayed.
