Graphics / Getting a portion of A sprites bounding box for collision detection

« on: May 20, 2018, 02:14:59 am »

Hello. I have two sprites that I want to check for collision on. I was originally calling getGlobalBounds() on both sprites and checking if they intersected. This works fine except for the fact that the player sprites are holding a long weapon, so even if just their weapons are touching when attacking, it counts as collision. I want it so collision only happens when the weapon is hitting the other sprites body. Is there a way to get only a portion of the bounding box for a sprite and then see if it intersects with the other sprite? Thanks!

Graphics / Re: Differently sized sf::Texture's causing sprite to move

I hope you're using one texture with all the images on it and use the texture rect to extract the wanted section.

I will admit I was originally loading in all .PNG's into a vector of sf::Texture, which I know now was not a good idea. I compiled all the pictures into 1 png in photoshop and then changed the dimensions like you said and it worked perfectly! I'm ashamed I didn't think of that earlier. Thank you though! This is a much nicer solution

Graphics / Differently sized sf::Texture's causing sprite to move

« on: May 18, 2018, 12:04:02 am »

Hello. I have a Sprite that is made up of ~20 different .png's that my Sprite cycles through to create a 'running' animation. My issue is that a couple of the images have a bigger height then the rest of them. This causes the Sprite to move down vertically an inch or two. I'm guessing this is because a Sprite's origin is always relative to it's top left position, thus causing the sprite to move down because the top left remains in the same spot.

I have sorta fixed this by creating a variable called count that keeps track of what frame of animation the Sprite currently holds, and if it is on one of the bigger images, I manually bump the sprite back up to make it look like it never bounced down. I feel like this is really hackish and that there is a much more elegant way to fix this. Any thoughts? The only reason I don't want to keep this way of fixing it is because I have a bunch of other player sprites I want to use in my game and they all will have this problem and manually bumping all of the sprites up seems tedious and unnecessary.

I've attached a small clip showing what happens with my sprite.
