How do I figure out which image point C3 is referring to?

C3/Mobile Game

How do I know which image point the program is referring to?

I need image point 3 on log to spawn a spike ball at the spike balls image point 0. Does that make sense?

I made a graphic.

So when it reads Image Point in the add action code box, is it talking about the log's image point or the spike balls image point?

It's the image point on the log...you probably could've tried that before posting lol

Sadly, I did.

I know something else is wrong, but needed to know the image point thing first before looking for issue #2, 3, 4 ..... 20,000.

Thanks for the info.

Spawning makes the new object use the parent objects angle.

System create object is usually a better match.

Also you can't know an objects image point before you create the object.

Thank you for your reply.

I used system > create to create the log which is scrolling down the screen at a bullet speed of 400.

I can't figure out how to do system > create, a spike ball and set it's position to image point 3 of the log. I can't set the X and Y because the log is always moving ..... unless there's a formula for Y and X.

Worse yet, once I create the spike ball I want it to roll left until it falls off the log - which is difficult because I currently have the angle set to 90 so it scrolls down the screen with the log.

One problem at a time, right?

Use the log.ImagePointX(ImagePoint) and log.ImagePointY(ImagePoint) to get it there, it should work.

newt,

Thank you so much.

I have to figure out how to make formulas. They make sense when I see them, but my brain hasn't started to come up with them on it's own yet.

Thanks again.

These are not really formulas, they are called expressions (like properties). Expressions are super-useful, but you don't need to memorize them. There is a handy expression dictionary accessible from any dialog. Try browsing them and you'll be amazed by how many exciting things you can do with expressions!
