Graphics / Basic sprite questions
« on: July 01, 2021, 12:07:17 am »
I have a few basic sprite questions i'm a bit new to SFML.

So i want to display some kind of sprite and also be able to detect collisions, this sprite is a sort of abstract shape, with a transparent background in a rectangular png file.

so what would be the best way to go about this, i'm aware of several, I think its possible to just load the sprite into a sprite class, but my question is, would the transparent background be apart of the sprite still? for example, if something collided with the transparent background would that register as a collision to the sprite?

And i've found another way to roughly approximate the sprite with a convex shape, than load the sprite as a texture into that shape, but i was just wondering if this was necessary.

General / Help with animating non rectangular sprite
« on: June 30, 2021, 06:20:39 am »
I'm pretty new to sfml, I want to make a simple game.
One thing i'm having trouble with is complex sprites.

For example, in my game I want a cannon shaped sprite (one found online), that moves angles based on the users input. I also want a background, for example a blue sky. I roughly know how to animate a sprite, But as far as i'm aware, its pretty difficult to set the boundaries for complex shapes. If i put the cannon sprite in a basic rectangular shape, then wouldn't there be a rectangular boundary around the cannon sprite? and if I wanted it animated, i'm having trouble figuring out how I could put the background around the cannon, without this border.

If it wasn't animated, I could maybe just put the background inside the sprite itself. But even then, what if I wanted a moving background with clouds or whatnot?
