### Re: [Solved] Pointing at an object that's out of sight

@pgimeno it's not pickiness xD , it's an important pointer. That point-slope code has special cases for when the player and enemy are perfectly aligned on the X or Y axes (so this prevents a division by zero, or when the slope 'm' results in zero itself), but for the case you mentioned of the player...

### Re: Pointing at an object that's out of sight

This task can be solved by casting 4 rays, each to an axis-aligned line. The formula for line-line intersection is very simple when one of the lines is axis-aligned. That's a cool solution pgimeno, very fast and elegant. The method I came up with when thinking of this is more verbose and I think sl...

### Re: Making a progression bar

I think you can do this using Data objects, more specifically FileData, created by reading a file from disk with love.filesystem.newFileData . FileData is a subclass of Data, so you can know the amount of bytes that the loaded file data represents . You can also calculate the total bytes from all as...

### Re: Obstacles in game

Also, if you imagine yourself making more complex games in the future, it'd be interesting to invest some time in making simpler games first that will give you an easier challenge in learning different techniques, design patterns and such. There are two cool articles talking about this, not specific...

### Re: Obstacles in game

I am currently having trouble drawing random obstacle. I don't know how to write an algorithm that creates a obstacle that goes in my direction and crate new obstacle every few seconds. Hi. What have you tried already, can you show some code? The things you're asking are very simple, so maybe it's ...

### Re: Need help with making surface of image clickable.

You can see the same mistake in your other files. How about any time you write a " function somethingsomething() ", go ahead and already add the " end " that will close it, just so you don't forget that anything between the name and the end will belong to the body of that functio...

### Re: Need help with making surface of image clickable.

For every 'function' definition there needs to be an 'end' to close it. So when you do something like this: -- Call Backs -- function love.load() function Player.load() -- debug -- io.setvbuf('no') --Player Movement -- function love.update(dt) if love.keyboard.isDown('d') then Player.x = Player.x + ...
