    GML [SOLVED] Lengthdir Problem - Elements not moving properly in circle. X and Y don't match Sprite Origin.

    Hello! I'm having trouble with (probably) lengthdir. I spent so much time on it, but I just can't figure out what I am doing wrong. I thought that maybe someone can give me the reason this is happening. Basically I was trying to draw circles in front of the character, as hands and I used...

    GMS 2 Collision avoidance with lengthdir help

    Hello everyone, I have been making steady progress on a game I have been working on (mostly to learn) but it is an RTS style game. Most of the time I am able to debug enough to resolve my own issues, however, I am coming across a problem I cannot seem to think through on my own. Perhaps its...

    GML spawning a bullet while rotating

    when my player is at angles 0, 90, 180 or 270 the bullets look correct. if my player is between those angles then the bullet spawns off to the right/left of where it should be. var _xx = x + lengthdir_x(20, image_angle); var _yy = y + lengthdir_y(0, image_angle)...

    GMS 2 obj moves towards player then orbits it?

    Hi, my question in GML: I want to have an object orbit or swarm around the player object once it reaches it. My hangup is after the collision occurs would I then just use lengthdir to create the orbit? Or is there a simpler way? JB

    GMS 2 <solved> what is best usage of lengthdir?

    OK I have trying to use lengthdir, for attaching parts to an object and keeping them in place when I rotate the object. I thought I had this figured out. Until I began to try and align the objects and I found that the lengthdir code I have changes the x,y of the initial starting place as soon...

    GML [SOLVED] Shooting diagonally with collision_line

    Hi everyone. So I've been struggling with this for the last few hours, and after failing to find a solution elsewhere, I've decided to ask here: how do I check a collision with collision_line in other directions? Cardinal directions are easy, because it uses a rectangle, but I can't find a way...

    Swinging With Lengthdir_x, etc..

    I want to make the player swing from a fixed object. I have lengthdir set up and can make them rotate around it using the D and A keys but would like to add a form of physics to the whole system. i,e: Add the speed that they're travelling in a direction to when the grab onto the object and use...

    Legacy GM [SOLVED] Rotation with lengthdir, origin, one instance

    G'day G'day! I'm trying to rotate an object's sprite around its sprite origin (which I have set to be at the center of the sprite), but after I have first re-positioned it with lengthdir. The sprite is drawn correctly at the new location with the lengthdir functions, but the point (axis?) of...

    Locking an object to another based on its image_angle

    Hello, I'm trying to have an object 'locked' to another, so when the primary object rotates the secondary object will rotate around it at a fixed distance away from the primary. For example a rocket booster on the back of a ship. As the ship rotates the booster always stays at the back of the...

    Hi, so I've been trying to make an object_view be in the half of the distance between my object player and the nearest enemy so I can have more dynamic views. If solved I will do a max distance but that I can figure out myself. Here's my code and it just simply doesn't work as intended on...

I've posted what I think is the relevant code below. The x,y length_dir code I'm using shoots the flame from the...
