Stretching a sprite between two points.

[Pixel_Outlaw]

Hello,

I'm trying to draw a texture as a line. The texture is 4x8 pixels. It is a gradient for a laser line effect. It points right but that might be the problem.

Also I have a rounded end cap texture that must be rotated and placed at the endpoints. It points right but that might be the problem.

I need a function to rotate and stretch the texture so the edges will touch (x,y) and (x2,y2). Then the end caps are rotated and placed on.

I've messed with this for about 2 hours and between C++'s notion of direction in radians, SFML's notion of direction in degrees, and moving sprite x and y origins. Nothing seems to work.

Maybe you can find useful info there.

TheEnigmist,


This is not really the same thing. I need to stretch a texture from point a to point b.

Like this.
