Player Shooting on a Platform Game

[Turon]

I have been a bit puzzled about shooting. Ever played Mario? Well if you have he collides with the fire flower! And he can shoot left and right........HOW?

Kren made tutorial for that also, here: viewtopic.php?f=2&t=8681
Just use xvelocity instead of yvelocity.

[Turon]

Thank you Lcl! But i can only shoot right with the command

Code: Select all

yvelocity=-10;

well that go's right.... right? so please tell me the command to go right!

That doesn't make the actor go right. This does.

Code: Select all

xvelocity=10;

This is left.

Code: Select all

xvelocity=-10;

Up.

Code: Select all

yvelocity=-10;

Down.

Code: Select all

yvelocity=10;

If you want to shoot in two directions, what are you using as a direction variable? You can use the player's animation, like this.
player -> Create Actor -> Script Editor

Code: Select all

if(creator.animindex==4) // This assumes the shoot fireball animation is the fifth animation on your player
{
    xvelocity=10;
}
else
{
    xvelocity=-10;
}

**Note if you have ordered your animations properly this will work. If not, you'll have to use a direction variable. Also if you don't have a shot right, shoot left animation then you'll have to use % to find even odd (assuming your animations jump back from right, left, right or vice versa). This probably didn't make a lot of sense to you, but for it to I need to know your animation ordering, or how you distinguish direction.

Cooooooooooooooool!!!!!!!!!!!!!!

sky you said yvelocity=10;, you forgot the plus sign

[NightOfHorror]

same for xvelocity=10;, you forget plus sign

[skydereign]

I didn't need a +, I was setting xvelocity to equal 10. If xvelocity already equals 0, then they would do the same thing. But if xvelocity is already 10, adding the += would make it 20, which I don't want. So, using =10 and =-10 is exactly what I meant and wanted.

Yes but how does the fire ball change direction? like when my players animation is on player stop right the fire ball must shoot right. And when the animation is on stop left the fire ball must shoot left! HOW?

Ok turon, here is the basic method.
First do this. Go to some script editor, click variables, click add, name the variable dir, click ok.

Then add that to player key down right script:

Code: Select all

dir = 0;

And this to key down left:

Code: Select all

dir = 1;

Now add this to the shot's create actor script:

Code: Select all

switch(dir)
{
    case 0:
        xvelocity = 10;
    break;

    case 1:
        xvelocity =-10;
    break;
}

It is so simple.

Player -> Keydown -> Right:

Code: Select all

dir=1;

Player -> Keydown -> Left:

Code: Select all

dir=-1;

Shot -> CreateActor:

Code: Select all

xvelocity=dir*10;

This is even simpler

Oh, yeah, I thought of something like that, but decided to write the another one still.

Now how do you make it shoot only when you collide with the fire flower?
