Ball hiting & explosion

[Onyx]

Hi, i got two questions.

1. How to make a ball that explode only when hits a character (for example, dont explode when hit rock, or other ball)
2. I made a ball which explode on any contact, but when item is on the ground (even knife which is small) that ball always
hiting this item (height of this ball is like firen_ball) How to change that? I want that ball to evade items like knife without changing height.

Here's code. Please help guys

What you can do is giving the ball a special ITR I think, so that the ball catches the opponent and then explodes. I don't know how to do this from the top of my head, but I'm pretty sure you can find out by using search and look for it in the data changing forum

Also, welcome! It's always good to see there are still people joining the community that are interested in making new stuff

1. How to make a ball that explode only when hits a character (for example, dont explode when hit rock, or other ball)

If your ball ONLY needs this property and not including the 2nd one, you can simply modify the "hitting" frames. "hitting" is used when it hits character, "hit" is used when it hits another ball, "rebounding" if it gets reflected. R-LF2 Firen's D>A (firen_ball2) is a good example.

2. I made a ball which explode on any contact, but when item is on the ground (even knife which is small) that ball always hiting this item (height of this ball is like firen_ball) How to change that? I want that ball to evade items like knife without changing height.

There are a few ways you can do that, off the top of my head its about using itr kinds 3 or 8, but each method has its own disadvantages. Namely itr k3 is a grab itr(used by Louis D^J) so the attack becomes unblockable, while itr k8 will collide with any character regardless of team, yourself or even invisible players.

As Neocrypt said, you can search the mainsite for more info. Mouse over "LF2 Empire", then "Data Changing", and click the desired section.
