How to shoot animation from point A to point B

[Ferbguy]

I am working on a game. Im kinda stumped atm, having issues on grasping how to shoot a Animation shot from object 1 to object 2 where object 2 is changing slowly moving towards the nearest object 1. i am trying to draw a invisible line from object 1 to object 2 current position and play the animation along that invisible line. Am i even in the right nieghborhood.

I know y = m*x + b is the formula to find a straight line between 2 points but i'm not really sure if it would work for sprite movement. Chili explains it in lesson 10.

Though using trigonometry SOH CAH TOA you can get a direction from one point to another and move the shot the exact distance you want in that direction.

In fact I'm going to see if i can write a function that takes in 2 coordinates and finds the angle and distance between them, just for fun.

Well, i really did try but i can't get it to work. i wrote a function to move one point towards another with a variable speed, it compiled fine but broke when i ran it. Then while debugging, whenever i try to step into the function is tells me the source code is missing and i have no idea why.

Seems simple enough. Take the x and y distances and divide them by the number of frames you want the animation to last. Then add these values to you position for n frames, after which your object will be at its destination. Make sure you use floats and use logical rounding.

ok, i am going to try and see if i can get this to play from that angle, also one more thing, object a uses animation to simulate rotation bases off of mouse coords, use the same thing for both?

Interesting, haven't thought about chili's method before.
