Legacy GM [SOLVED] Fixing going diagonally faster in top-down game makes camera movement lag

[CornerLord]

Hello.
I'm making top-down game and when I "fix" speed when moving diagonally it makes camera lag if I move diagonally. I have obj_camera and I have set view to follow it in room settings. I have also tested without camera object but it doesn't help.

Here is my code for player movement:

//Player Movement
hspeed = walkingSpeed * (right - left);
vspeed = walkingSpeed * (down - up);

// Speed fix when pressing 2 buttons at the same time
if abs(hspeed)==abs(vspeed)
    speed = abs(hspeed);

I have tried to use

if speed >= walkingSpeed {speed = walkingSpeed }

but it doesn't help.

Had a similar problem with the same thing. Here's the code that I used as a solution to the problem. Maybe you could use something similar?

if(up && left) || (up && right) || (down && left) || (down && right) {
    mspd = 3;
}else{
    mspd = 4;
}

N.B mspd is variable to determine how fast the character can move. Default is set to a speed of 4, but, when the character is moving in an angle, the speed is reduced to 3. Seems to work OK, although there's probably a better solution. Hope this helps!!

hspeed = walkingSpeed * (right - left);
vspeed = walkingSpeed * (down - up);

if(up && left) || (up && right) || (down && left) || (down && right) {
    walkingSpeed = 2.825;
}else{
    walkingSpeed = 4;
}

This works fine but maybe not the best solution xD I have to use 2.825 instead of 3 because if I use 3 then the speed is 4.24 when moving diagonally (+0.24 to normal speed) :/

Edit: It doesnt work... Camera lags still when moving diagonally

Can you paste the code for your camera object?

The problem is that the camera is moving to the original spot of the player, then the player moves.
Put the code in the END step event.

What I do is move the view inside the player's code, after the movement scripts.

Spoiler

I got your point but can you tell me how to control view inside the player's code

And here is my obj view's code

x += (obj_player.x-x)/5;
y += (obj_player.y-y)/5;

EDIT: I got it I put

view_xview[0]=x-(view_wview[0]/2);
view_yview[0]=y-(view_hview[0]/2);

to end step event in player object. It works now.
But my new problem is how to make it "smooth" because now I can't use the settings in room editor

Use lengthdir_x/y to do the movement rather than using hardcoded values...

var hspd = right - left;
var vspd = down - up;
x += lengthdir_x(walkingSpeed, hspd);
y += lengthdir_y(walkingSpeed, vspd);

lerp() is a really good function for this! It would even make it more smooth than the built-in room camera.

var targX = x-view_wview[0]/2;
var targY = x-view_hview[0]/2;

view_xview = lerp(view_xview, targX, 0.1);
view_yview = lerp(view_yview, targY, 0.1);

Thanks for everybody who helped me!

And btw
var targY = x-view_hview[0]/2; should be
var targY = y-view_hview[0]/2; @Bingdom

xaxis = keyRight - keyLeft OR xaxis = gamepad_axis_value(0, gp_axislh);
yaxis = keyDown - keyUp OR xaxis = gamepad_axis_value(0, gp_axislv);

var dir = point_direction(0, 0, xaxis, yaxis);

hspd = lengthdir_x(abs(xaxis * moveSpeed), dir);
vspd = lengthdir_y(abs(yaxis * moveSpeed), dir);

x += hspd;
y += vspd;
