You can also use the abbed variable to get info about what the player has picked. Step event: // Move object if currently grabbed Global Left Released event: // Stop dragging Left Pressed event: // Check if instance can be dragged So, instead of a true/ false approach, we have a noone/ id variable that specifies which particular instance is being moved around.

It will save your sanity in the long run, trust me. since I dont understand the commands in the program, Im using. This variable will hold the id of the instance that must move around. Im using game maker studio 2 to create a dungeon game as a programming experience, and I am trying to make an enemy target the player. To do so, we can use a global variable instead of an individual flag to tell what instance is picked by the cursor, and move it accordingly: abbed = noone The code works fine so far, except if multiple instances are overlapping when you click, they will all snap to the mouse position! To prevent this, we must make sure one instance only is 'grabbed' when clicking before dragging it. Now objects are dragged only if mouse click happened inside their collision mask. We can do this by splitting the code between Left Pressed event: // Now instance can moveĪnd Global Left Released event: // Now instance must stopįinally our Step event will loop like this: // Move instance if selected We set its value to true when the mouse button is pressed and conditions are met and set it to false when the mouse is released.

We give every instance a variable, with a starting value of false: grabbed = false The code above doesn't take into account whether an instance is actually being clicked on by the user, it cares only about the button click itself. Or at least, this is the GML equivalent of what is happening. If (mouse_check_button(mb_left) & position_meeting(mouse_x, mouse_y, self)) If all your objects move at the mouse position at the same time, probably their Step event looks like this: // Click and drag object
