Hello my game current have fps,coin system,traps,checkpoint,life system,fade block,falling block and only two problem i have now.



My first problem is push ups block that i use from other engine to my new one.

End step script
GML: 
// Actual collision checks + movement
var i;

// Vertical
for (i = 0; i < abs(v); ++i) {
    with (obj_Stick) {
        if (place_meeting(x, y + 1, other.id)) {
            if (!PlaceMeetingException(x, y + sign(other.v), obj_GroundCol, other.id))
                y += sign(other.v);
        }
        
        if (place_meeting(x, y - 1, other.id))
            y += sign(other.v);
    }

    if (!place_meeting(x, y + sign(v), obj_GroundCol))
        y += sign(v);
    else {
        v = 0;
        break;
    }
}

// Push stacks of blocks
with (oIce) {
    if (instance_place(x, y + 1, oIce))
       h = (instance_place(x, y + 1, oIce).h);
}

// Horizontal
for (i = 0; i < abs(h); ++i) {      // Move stacks
    // UP slope
    if (place_meeting(x + sign(h), y, obj_GroundCol) && !place_meeting(x + sign(h), y - 1, obj_GroundCol))
        --y;
    
    // DOWN slope
    if (!place_meeting(x + sign(h), y, obj_GroundCol) && !place_meeting(x + sign(h), y + 1, obj_GroundCol) && place_meeting(x + sign(h), y + 2, obj_GroundCol))
        ++y;       
        
    if (!place_meeting(x + sign(h), y, obj_GroundCol))
        x += sign(h);
    else {
        // Push other push blocks
        if (place_meeting(x + sign(h), y, oIce)) {
            with (instance_place(x + sign(h), y, oIce))
                if (instance_exists(obj_Stick))
                    h = obj_Stick.h
        } else
            h = 0;
        break;
    }
}

///////////////////////////////////////////////////////////////////////////////
Scripts
PlaceMeetingException
GML: 
var exception = argument3;

with (argument2) {
    var callingObj = id;
    
    if (id == exception)
        continue;
    else
        with (other)
            if (place_meeting(argument0, argument1, callingObj))
            return true;
}

return false;
OnGround
GML: 
/// OnGround();

return place_meeting(x, y + 1, obj_GroundCol);
Approach
GML: 
/// Approach(start, end, shift);

if (argument0 < argument1)
    return min(argument0 + argument2, argument1);
else
    return max(argument0 - argument2, argument1);


Second problem is worst part about jumping


End Step jump code

GML: 
// Launch player
if (place_meeting(x, y - 1, obj_Stick)) {
    // Shake screen
    with (oCamera) {
        alarm[0] = 10;
        screenShake = true;
    }

    // HIGH JUMP!
    with (obj_Stick)
        
      
    
    // Particles
    var i;
    for (i = 0; i < 8; ++i)
        with (instance_create(x + 8 + random_range(-8, 8), y, obj_Particle_Dust))
            direction = 90 + random_range(-45, 45);
}

// Launch push blocks (copy + paste)
if (place_meeting(x, y - 1, oIce)) {
    // Shake screen
    with (oCamera) {
        alarm[0] = 8;
        screenShake = true;
    }

    // HIGH JUMP!
    with (instance_place(x, y - 1, oIce)) { // Target specific push block
        v = -14;
        if (place_meeting(x, y - 1, obj_Stick)) {
            obj_Stick.y -= 14;
        }
    }
    
    // Particles
    var i;
    for (i = 0; i < 8; ++i)
        with (instance_create(x + 8 + random_range(-8, 8), y, obj_Particle_Dust))
            direction = 90 + random_range(-45, 45);
}



if place_meeting(x+hspeed,y,obj_Stick)
{
    hspeed = -hspeed;
}

//vertical
if place_meeting(x,y+vspeed,obj_Stick)
{
   vspeed = -vspeed;
}
This code give me error

// HIGH JUMP!
with (obj_Stick)
v = -jumpHeight * 2;

When i remove a v = jumpheight my player just shakescreen not jump automatic like on this video

GML:

Okay... where are you setting obj_Stick.jumpHeight? You haven't shown that part. I suspect that's because it doesn't exist.

Show the assignment of a value TO jumpHeight. You have not shown this. You must show this.

Hm i cant find this part i have only this up and this code in my obj player
GML:

state = "StandRight"; // set the players initial state
globalvar showDebug; // debug overlay

moveSpeed = 10; // players move speed
ySpeed = 0; // players yvelocity speed
grav = 1.2; // players gravity
wallGrav = 1.5; // gravity while on wall(used for wallslide)
jumpHeight = 16; // height the player will jump
fireRate = 30; // rate of fire(lower = faster)
bulletSpeed = 40; // speed of bullet

canJump = true; // can the player jump?
canDoubleJump = true; // can the player double jump?

This part is working

    // HIGH JUMP!
    with (instance_place(x, y - 1, oIce)) { // Target specific push block
        v = -14;

You have to tell the program what value you want the variable to have, if you want to use the value that the variable has. You need to assign a value to the variable. If you have never done this, then it has not been done. It needs to be done. You need to assign a value to the variable before you use it.

I see that you're assigning a value to jumpHeight in the obj_player. The obj_Stick doesn't know about that, because it is an obj_Stick and not an obj_player. If you want obj_Stick to use the jumpHeight in obj_player, then you need to tell it to do that. If you want obj_Stick to have its own jumpHeight, then you need to set it. You must do one or the other of these things.
