instance_create when mouse hover

[shmurl]

On my intro screen, I have users choose a level. When the mouse hovers over a level, I want an object (obj_points_per_level) to pop up with some info regarding that level. When the mouse isn't hovering over the level the pop up should be destroyed.

I created an obj_points_per_level with different sprites to display the info for each level.

The problem I am encountering is that it will only popup when I mouse over one of the levels and not the other. I imagine the reason is because I wrote that when the mouse isn't hovering over the obj_letters, the obj_points_per_level gets destroyed. Which must be overwriting the code (to create a new obj_points_per_level) when the mouse hovers over the obj_words. I just can't figure out a solution. Is there a more efficient way to do this, perhaps using a switch?

This is the code that I have (I'm trying to keep the code all in one object - obj_choose_level). Note, I will add more code with the other levels once I have the proper code


if popup == false {with (obj_points_per_level)instance_destroy(); popup = true;}; //popup is initialized in the create event

with (obj_letters)
{
if position_meeting(mouse_x,mouse_y,obj_letters) && obj_choose_level.popup = true
{
instance_create(x,y-70,obj_points_per_level);
with (obj_points_per_level){image_index = 1};
}
else if !position_meeting(mouse_x,mouse_y,obj_letters){obj_choose_level.popup = false};
};


with (obj_words)
{
if position_meeting(mouse_x,mouse_y,obj_words) && obj_choose_level.popup == true

{instance_create(x,y-70,obj_points_per_level);
with (obj_points_per_level){image_index = 1};}
else if !position_meeting(mouse_x,mouse_y,obj_words){obj_choose_level.popup = false};
};

game maker has a mouse enter and mouse leave functions for this.

You could use the Mouse Enter and Mouse Leave events for each of the hoverable objects, this lets you split the code up in a more manageable fashion. If you want to keep using the code, I'd use a break statement after each time you DO create a points_per_level object to prevent checks for creating/destroying any more. (See The "Break" Statement). Another idea is to make a parent object for all your hoverable objects, and only destroy the points_per_level objects when there is not an instance of that parent under the mouse position - all the children will count as the parent for the purposes of a check like that.

@jackhigh Thanks, that is what I am looking for, but I want to do it with code.

@Yal Thanks!
I understand what break does, but I don't understand how to use it (even after viewing the link)
I created an obj_parent_level for the children obj_words and obj_levels.
I placed the following code into the parent step event

if position_meeting(mouse_x,mouse_y,id)
{
instance_create(x,y-70,obj_points_per_level);
with (obj_points_per_level){image_index = 1};
}
else {with (obj_points_per_level)instance_destroy();}
//the above code is giving me the same issue as before, it will only create the instance when hovering over one of the objects

so I changed it to this
if position_meeting(mouse_x,mouse_y,obj_parent_level) //this line is the only line I changed. From id to obj_parent_level.
{
instance_create(x,y-70,obj_points_per_level);
with (obj_points_per_level){image_index = 1};
}
else {with (obj_points_per_level)instance_destroy();}

It does work when hovering over each object, but now whenever mouse hovers over one object it creates the popup (obj_points_per_level) over both obj_words and obj_letters. I only want it to popup over one at a time

EDIT: I'd love to learn how to use the break statement, if you have the patience to explain it
