[SOLVED]Moving platform help needed. Player slides off platform!

[pixeltroid]

The platforms move the way I want them to but whats happening is that when the player jumps on the moving platform, he just slides away to the right!

objects used:

1. obj_movingplatform
2. obj_player
3. obj_blocker (an invisible object placed at the end of the moving platforms path)

-------------------------------------

1. for obj_movingplatform

Create:

vspeed = 2

Step:

with (obj_player)
{
if (place_meeting(x,y-4, obj_blocker))
{
with (obj_movingplat)
{
vspeed = 2;
}
}
}

Collision with obj_solid (used for floors, walls, ceilings etc):

if (vspeed > 0)
{
vspeed = -2;
}

else
{vspeed = 2;
}

if (place_meeting(x,y-1,obj_player))
{
obj_player.y -=5;
}

Collision with obj_blocker that limits movement of platform is same as above



2. For obj_player

Collision with obj_movingplatform

{
move_contact_solid(direction, 3);
vspeed = other.vspeed;
}

What am I doing wrong with the code???? How can I modify the code to make it work?

using the built in variables cause problems. and you don't need the blocker object. set the platform in the center position of where you want it to be and in its create event say

dir = choose(-1, 1);
timer = 0;

then in the step event

timer += 1

if timer > (when you want the object to change direction)
{
     timer = 0
     dir *= -1;
}

x += dir * (whatever speed you want it to be)

unless you have walls then do the place meeting thing.

As for the player moving with the platform just have the normal player movement actions then on the player put

if place_meeting(objPlayer.x, objPlayer.y + 1, objPlatform)
{
     x += (speed of the platform) * objPlatform.dir
}

sorry I just saw you have a vertically moving platform, just swap the x's and y's and you'll have the same solution

Hi. I tried your code. The platform moves properly but now my player gets stuck on it :/

 

[ThePropagation]

Do you have any platform collision restriction on the player character? you can remove that

hey... your method worked....I just changed "x" to "y" (since its a vertical platform).

Just one thing...how do I make it work with obj_blocker? Im asking because its easier to control the distance the platform moves...and that way I dont have to calculate timers!

 

[ThePropagation]

if place_meeting(objPlatform.x, objPlatform.y + vertSpeed, objBlocker)
{
dir *= -1;
}

 

[pixeltroid]

if place_meeting(objPlatform.x, objPlatform.y + vertSpeed, objBlocker)
{
dir *= -1;
}

what do I set the vertSpeed as in the create event?

 

[pixeltroid]

if place_meeting(objPlatform.x, objPlatform.y + vertSpeed, objBlocker)
{
dir *= -1;
}

Hey. I just added

dir *= -1

into the collison event of obj_movingplatform when it touches the blocker object and now its working great!

Thanks a ton for your help!!

the vSpeed would be how far ahead you want the platform to turn around. Glad you got it working

Hi, Im using Dnd, my player just slides off the platform when they stand on it. I just give the moving platform a direction to move in, and when it gets to the end of its path, it reverses its direction, but when the player stands on the platform, they just slide off, even when the moving platform is a solid.
