Godot making test questions

azzkicker1994

My goal is to have Godot make 2selections from 100 simple images (shapes). Using the 2 images, there will be 5 possible "answers" 4 of the answers will be the same image and the image that is different is the correct selection. I've managed to get 5 test images to see if i can make it happen, and i have my background and 5 image fields as well as the proper "spawn" locations (i managed to use a random spawner, but it's typically 4 of the same images" any help would seriously be appreciated, im using it as a studying tool. For the SIFT if anyone was interested.

OK, so are you looking for someone to do it for you? In which case I can move this to the appropriate category(professional trade).

Or are you asking how to go about developing such a thing? In which case I'd say your question is perhaps a bit too broad.

Start by figuring out how to divide it up into smaller tasks that can be done in steps and try to figure out the optimal order for completing these tasks by following the steps. If you need any help with any one of these steps then it's a good time to ask more concise questions about achieving the specific task. This also makes it easier to give a clear and concise answer.

I see, I apologize for the vagueness. I'm asking for advice, and I guess I don't know where to start. It all seems so simple! My first hurdle I would say is getting Godot to randomly select 2 images, randomly duplicate 1 of the images to place in 4 of the 5 spots (randomly of course) and then place the second image in the 5th spot. What is a good way to show my current coding so you can see what I'm working with?

azzkicker1994

its a basic background, but you can see where the image slots are.

You can either copy and paste code in your post, then highlight(select) all of it and press the code option under the format menu(paragraph icon), or the best is if you can share a minimal project only including the parts necessary to show your problem.

    			var rand = floor(rand_range(0, possible_pieces.size()));
    			#instance that pieces from array
    			var piece = possible_pieces[rand].instance();
    			add_child(piece);
    			piece.position = grid_to_pixel(i, j);
    			
    
    func grid_to_pixel(column, row):
    	var new_x = x_start + offset * column;
    	var new_y = y_start + -offset *row;
    	return Vector2(new_x, new_y);
    
    
    
    # Called every frame. 'delta' is the elapsed time since the previous frame.
    #func _process(delta):
    #	pass

this is essentially all that there is so far, thank you for the help by the way.

Could you describe your scene/node hierarchy a bit, I'm trying to recreate it on my end here.

azzkicker1994

I'll do my best. I have one "scene" as node2d with a Sprite child node. I used that to create 5 inherited scenes and placed my pictures in the Sprites texture field. I named each one "piece_1" though 5. I think I bit off a bit more than I could chew in terms of scripting.... I'm doing my best in terms of learning/research. here are the 5 images I've been using.

Yes I figured that out from your code, but the scene where your script is attached, Is that just a Node2D? or is there something else going on in there too?

For the shapes I just created polygon2Ds representing numbers 1 through 5 which for my purposes should be functionally as good.

azzkicker1994

no funny business, its all node2d. My "grid" node is just a node 2d, and that's were the script I pasted is located, its a child of the same node as my "background" image.

Megalomaniak

Hmm, ok. I've been busy, but hopefully I can afford to take a hour or 2 to look at it tomorrow. If someone else wants to chip in and look at this though, hey. That would be great too.

azzkicker1994

I guess when Megalomaniak comes around, people steer clear! No rush, I'm using it to help me study, and lord knows I have plenty else to study. thanks again for helping me out

Megalomaniak

Ok, I've had a chance to take a quick look and it is working far as I can tell, so I guess I'm confused what your actual problem is. Getting it to only show 2 out of 5 shapes? Or something else?

azzkicker1994

I get off work at 5 and i'll take a reference picture

Megalomaniak

Ok, well, this should kind of work, except you can end up with a situation where it's all of the same shapes...

extends Node2D

export (int) var width = 5;
export (int) var height = 1;
export (int) var x_start = 420;
export (int) var y_start = 270;
export (int) var offset = 48;

var possible_pieces = [
preload("res://Scenes/piece_1.tscn"),
preload("res://Scenes/piece_2.tscn"),
preload("res://Scenes/piece_3.tscn"),
preload("res://Scenes/piece_4.tscn"),
preload("res://Scenes/piece_5.tscn")
];

var all_pieces = [];
# Called when the node enters the scene tree for the first time.
func _ready():
	randomize();
	spawn_pieces();


func spawn_pieces():
	var rand
	var piece
	
	for i in width:
		if i < 2:
			for j in height:
				rand = floor(rand_range(0, possible_pieces.size()));
				piece = possible_pieces[rand].instance();
				self.add_child(piece);
				piece.position = grid_to_pixel(i, j);
		elif i >= 2:
			for j in height:
				piece = possible_pieces[rand].instance();
				self.add_child(piece);
				piece.position = grid_to_pixel(i, j);
		

func grid_to_pixel(column, row):
	var new_x = x_start + offset * column;
	var new_y = y_start + -offset *row;
	return Vector2(new_x, new_y);

edit: oh, and the first one is always the correct answer...

Megalomaniak

Further tips I can give are that to check if the user is picking the correct answer you can add the correct node to a group named say "correct" for an example, and that you want to pick first two of the potential picks and add them to another array and fill the rest of the array with the incorrect node of the two, then use array sorting to faux-randomize it again and spawn from that one in order instead.
