STEP 2: DEALING DAMMAGE

Find the project file for this part @ http://scratch.mit.edu/projects/archmage/76631

Now that your AI controlled sprite can move you will want it do deal damage.

To do this put the following code on the player2 sprite.

<when green flag clicked>
<set{ health }to( 100
<switch to costume[ idle
<forever if> <(  <{ nearPlayer }> <=> 1 )>
<switch to costume[ idle
<wait( 0.1 )secsc>
<set{ attacking }to( 1
<switch to costume[ attack
<wait(0.1)secsc>
<switch to costume[ idle
<set{  attacking }to( 0
<wait( 0.3 )secsc>

<when green flag clicked>
<forever if> << <touching[ player1  <and>  <( <{ attacking }> of player1 <=> 1  )>  >>
<change{ health }by( -5
<wait( 0.2 )secsc>

And put this code on the player 1 sprite.

<when green flag clicked>
<set{ health }to( 100
<switch to costume[ idle
<forever if> <(  <key[ space ]pressed?> )>
<switch to costume[ idle
<wait( 0.1 )secsc>
<set{ attacking }to( 1
<switch to costume[ attack
<wait(0.1)secsc>
<switch to costume[ idle
<set{  attacking }to( 0
<wait( 0.3 )secsc>

<when green flag clicked>
<forever if> << <touching[ player2  <and>  <( <{ attacking }> of player2 <=> 1  )>  >>
<change{ health }by( -5
<wait( 0.2 )secsc>

Variables that are needed for this part on both sprites are

health- set the health for each player which will decrease as damage is taken
attacking- used to check if a sprite is attacking

Now for the code explanation

<when green flag clicked>
<set{ health }to( 100
<switch to costume[ idle
<forever if> <(  <{ nearPlayer }> <=> 1 )>
<switch to costume[ idle
<wait( 0.1 )secsc>
<set{ attacking }to( 1
<switch to costume[ attack
<wait(0.1)secsc>
<switch to costume[ idle
<set{  attacking }to( 0
<wait( 0.3 )secsc>

The first thing this code does is set the health variable to 100 and sets the costume to the idle costume. Next, if the the sprite is near the player it will go into the attacking sequence. In the attacking sequence the costume is first set to idle then the attacking variable is set to 1 then the costume is set back to idle and the attacking variables goes to 0 again, also there is a small 0.1 second break between each costume change and a 0.3 second break at the end of the loop to prevent rapid attacks.

<when green flag clicked>
<forever if> << <touching[ player2  <and>  <( <{ attacking }> of player2 <=> 1  )>  >>
<change{ health }by( -5
<wait( 0.2 )secsc>

All this code does is check to see if the opposing sprite has it's attacking variable set to 1 and is touching the sprite. If the condition is true then the sprite's health variable  decreases.

And the scripts on the player1 sprite have similar functions except that the attack sequence is executed when the space bar is pressed.

So now what you should have is a opponent that attacks whenever it comes close to it's opponent. It is impossible to beat this opponent so next I will tell you how to create a reaction time for the computer controled player.

I am now programming this program demonstrated in this tutorial myself. Let up finish it then you can look at it in action.

Can i help make it? I am pretty good at programming

the game

the fighting game al tutorial

WOW!! this is good progrmaing i will try to use this... (i think i start with this
<touching color[ part]    )

ok i wll try harder

Ok, I admit I can read most of it but 2 things. number 1 is that to me it kinda looks not very clear though clear enough to read. Number 2 is when is says in the second part explained:

Change x velocity by: (accelcpu multiplied by ___)

All it says there is well, nothing,so what goes there? also what do you set the variables maxVelocity and accelCPU to?

Hey dude, can you reply to this or what?

Well I think here when it says accelCPU multiplied by, the picture is hiding the number

Hey, you should follow how the real smash bros game works, not just dealing damage, the more damage then more change of x velocity of other player when you attack him. And if he has over 300 damage you will do a super more powerful attack than usual and 100% chance 1 hit K.O.

Archmage - i really like this way of tutorials...

Very nice tutorial once again, can't wait for third part. It's very clear and I like the fact that you explain what is happening then just a bunch of codes. Well done and thanks.

<if> <( <{ xVelocity  }> <>> 0 )>
<point in direction( 90
<else>
<point in direction( -90

This script will make the sprite face right if it is moving right and face left if it is moving left.

Thats the end of step 1. I'll continue this later.

If you are pointing direction -90, than wouldn't you be upside down?

You have to select left and right directions only.

P.S. You have horrible handwriting.

I wouldn't say that if I were you.
That was written on the computer.

When you multiply a number, e.g., 5, by -1, the number gets reversed: 5 changes to -5.

That makes the sprite either increase it's xVelocity (Change x velocity by: accelCPU) or decrease (Change x velocity by: accelcpu multiplied by -1), i.e. move right or left.
