Triple Jumping in Game Maker, also other stuff

I read through other topics on triple jumping, but I still need some help. I would like to have a triple jump variable that goes up once every time the player hits the ground after a jump, but I don't know how I would do this.

I also need to know the simplest way of making wallkicking work. I've never been able to figure it out.

The final thing I need to know is much less complex. I just need to know how to make the player ease in and out of movement (i.e. making him slide slightly after he stops running).

Also, don't give me code, just explain a way of doing these things. If you give me code, I'll be tempted to copypasta. Then I won't learn anything, will I?

So yeah, it'd be cool if someone could explain any of this to me.

Wall kicking is simple.

Check for two things in the jump button:
1. Place below the player is free
2. Place directly to the left or right of the player is occupied by a wall

If both these conditions are met:
1. Set the vertical speed to a negative number
2. Set the horizontal speed to a positive or negative number, respectively (depending on which side the wall the player is kicking off of is on).



For triple jumps, make a variable like "jump". In the step event:
1. Check to see if the ground is directly below the player
2. If it is, have jump equal 3

In the jump button:
1. If the variable jump is greater than 0, subtract 1 from the variable jump.

This way, the triple jump is reset every time the player is directly above the ground, and if jump hits 0, you can't jump in the air anymore.

How would I make it so the value of jump actually effects the height of the jump?

It was a typo. I've fixed the post.

And in the jump key:
1. If the variable jump is 3, set the vspeed to -7
2. If the variable jump is 2, set the vspeed to -5

And so on.

jump key:
if jump=0
{
jump=1
vspeed=8+myjump
}


step:
if position_meeting(x,y+1,ground_obj) and jump=1 and vspeed>0
{
jump=0
myjump+=2
alarm[0]=10
}
if myjump>=3
{
myjump=0
}



alarm 0:
if vspeed=0
{
myjump=0
}

do you get that?

He specifically asked for no code.

You've been really helpful, but I still have a problem :[

For whatever reason, the character automatically does a triple jump for every jump. If you want, I can PM you the gmk so you can see what I did wrong.

By the way, the wall kicking worked perfectly, thank you

Sure, I'll take a look at it. Could very well be my fault, actually.

PM'd it to you.

did you look at my post?

You had the wall jumping numbers backwards. It should have started at 3 and worked its way down to 0.

However, you may be wondering why I set global.variable_triplejump to "2". I did this because the step event reset the jumps to 3 immediately after the jump. To avoid having 4 jumps, I just subtracted a number straight off the top, so the counter starts at two.

In other words, the first jump counts towards one of the three, so you only need two more jumps in the air.

Oh hey, I made my own triple jumping example
It uses super simple code

But yea thats still code

I loled for some reason.
