Question on how to make an actor jump properly?

kajuto

Hi!!! thanks in advance and i made this actor and 2do actor that i can jump over this one, but after that i can't jump again, it like stick to the actor with the code below. How can i make the 2do actor to jump again?

constrain X position to AAA*cos(self.time*BBB)+CCC

How it works:

AAA = the amount of movement.
BBB = the speed of the movement.
CCC = the centre (orgin) of the left to right movement.

kajuto

Hello there!!! how you doing? i need a little help please

i recently made a actor that move from x value to another x value (left to right & viceversa) the code i used is this:

Timer:
every 1.5 seconds run to completion
Rule:
Att : selfpositionX = 531.264
-Change Att 
  -selfright&left to false
Rule:
Att: selfright&left is true
- Interpolate
  - selfpositionX to 531.264
-duration 1 functon: linear
Rule:
Att: selfpositionX=808.502
-Change Att
-selfright&left to true
Rule:
Att: selfright&left is false
- Interpolate
  -selfpositionX to 808.502
-duration 1 second function: linear

I just want to move from one side or the other and up and down for another platform, because i plan to use 2 type of platform, one up and down viceversa; and another left to right viceversa. Also when i jump on top of it , i can jump again , because when i jump over, it stick to it.. =-( help please and i appreciate

Try this for a more simple left to right move:

constrain X position to AAA*cos(self.time*BBB)+CCC

How it works:

AAA = the amount of movement.
BBB = the speed of the movement.
CCC = the centre (orgin) of the left to right movement.

Tyran, if i do what you told me, the second actor can jump on top of it? i don't' mean collide, i mean when the 2nd actor on top of the 1st one it can jump over the same actor , like mario jump on top of the platform and can jump again in it

Clouds

if i do what you told me, the second actor can jump on top of it?

I have no clue.

kajuto

U don't understand my explanation or u don't know how to do it? Just in case, when the actor jump over the other and move together from one side to another I can jump again whenever I want to just to evade a obstacle or something

Clouds

You need to help people to understand your problem.

Take some screen shots of the code + make a video of the problem.

kajuto

1) I have a hero actor that i can move left and right and also a jump button.
2) i have a platform that move left and right using this code:

Contraint Att
- Self.position.X to 100*(self.Time*20)+450

the prob is this: when the #1 actor(hero) jump over the #2 actor i tried to follow it movement, which it find. the problem is here, once i'm over the #2 actor i can't jump again to another platform

Taidaken

maybe you only have it setup to jump when its only touching the ground and not the platform that moves..?

Clouds

1) . . . using this code:
Contraint Att
- Self.position.X to 100*(self.Time*20)+450

Great code ! (I even remember writing it for you !)

the prob is this: when the #1 actor(hero) jump over the #2 actor i tried to follow it movement, which it find. the problem is here, once i'm over the #2 actor i can't jump again to another platform

Someone might be able to help you, there some very intuitive people around here, but as we can't see the code or a video of the issue it could be just about anything ! People will have to ask you lots of questions about how you have things set up and working before being able to offer any advice - lots of people can't be bothered to do that.

Taidaken, thanks, i forgot to tag the other platform, that's why i can't jump over in the moving platform. Tyran , sorry to bother you so much.

I have a Score display , that i want to reset to 0

the coin that collect i use this code:
Rule (overlap or collide with hero)
-change att
-game.colletacableitem to game.collectableitem+10
- destroy

each time, i collected the coin, it's counted me +10, how can i reset each time i play the first level or even i restart the scene

Clouds

Tyran , sorry to bother you so much.

No problem at all !

how can i reset each time i play the first level or even i restart the scene

On the rule that restarts the scene or takes you to the first level . . . . place this:

Change Attribute: game.colletacableitem to 0

jomedia

i think you can change the score value when you touch the reset button change attribute and make the score value to 0

again

thanks Tynan and Jomedia!!! Tynan, if i pay you every time i ask you to help me or do something from scratch, would like to accept it? i pay through paypal

there is a maybe a stupid question, but till now i don't know how i calculate the scene x or y distance for example, the platform below:

i don't know, how i should know the x value or y value, for the 450 for example, because sometime i want to move from let say x=200 to 800 it move from another x value instead of where i want it to be

Let me make you an illustration . . . . I will be back (have my $50,000 ready )

kajuto

Thanks in advance to do me a big favor!!! really , would you like the offer? because each time i ask something , sometime nobody answer me or even take a lot of time to answer my doubt

Clouds

would you like the offer? : No money for me ! It's all free !


Does this make sense ? . . .

Clouds

So . . . AAA*cos(self.time*BBB)+CCC

 

AAA = the amount of movement.

BBB = the speed of the movement.

CCC = the centre (orgin) of the left to right movement.

"for example, because sometime i want to move from let say x=200 to 800 it move from another x value instead of where i want it to be"

200 to 800 = 600 pixels of movement (AAA)

The centre of 600 pixels is 300 pixels.

So to get 200 to 800 . . . . . 

300*cos(self.time*BBB)+500

. . . . . . . . . . . . . . . . . . . . . . 

Why 300 ?

You want 600 pixels of movement - 300 left and then 300 right.



Why 500 ?

When you move 300 pixels left (from x=500) the actor will go to x=200.

When you move 300 pixels right (from x=500) the actor will go to x=800.

kajuto

Wow, now I get it . Thanks a lot I'm very appreciate your help .!!

1) Do know any site that explain all the expression that GameSalad use like cos, sin , random, ect ect ??

2) How I calculate the distance or pixel where i put an actor to another segment in the scene editor ? For example Autodesk Maya or other program have a Guide Rule so I know where I'm putting a actor and know the distance, ect...

Nice pig..lol

Tyran i like a lot the explanation about the pixel, but inside the Scene Editor how or there is a way that i can activate a rule or something? because when I'm doing the moving platform i have to guess where 200 pixel it might be for example

There is no rule, no grid, no guides . . . nothing. In this respect GameSalad is worse than a typical text editing utility from 1996.

To place an actor precisely at X=200 . . . . . double click the actor in the scene and change it's X position value to 200 in the attributes panel on the left hand side of the screen.

kajuto

Jajajaj wow I can't believe I have to use a actor as a rule or grid for that jajaja thanks I imagined it might be that way but I just want to someone to confirm me.

Tyran. U know the code that u help me AAA*(selftime*BBB)+CCC ,Supposely I use that okay... I don't the platform to move until the hero actor is close enough to the platform then he can move. Is like the tutorial made by tshirtbooth using magnitude..

Is this a question ?

kajuto

yes, sorry LOL forgot the ??

i want when the hero actor is very close to the platform, then the platform start to move down so the hero can walk on top of it...

kajuto

Tyran the code that you gave me , that it work with Y axis? because i need one for up & down...please

Clouds

Are you joking ? )

Before I answer that, can you answer me this question, I want to know if I can use capital letters on this forum, not just one at the start of the word (like: This) but I want the whole word to be in capitals, do you think this is possible, have you tried anything like this ?

Clouds

yes, sorry LOL forgot the ??

i want when the hero actor is very close to the platform, then the platform start to move down so the hero can walk on top of it...

I think the magnitude tutorial by tshirtbooth that you mentioned should help you work that one out - you might even be able to do it without magnitude just using the actors 'X' position.
