onlyIf Pre Condition

[lukicdarkoo]

It would be great to have onlyIf pre-condition as it is more readable than skipIf (in most situations). The main problem is a "collision" with the skipIf pre-condition. They can be mutually exclusive, but maybe somebody has a better idea.

I 100% agree.

Sometimes, to avoid the reverse logic, I use successIf and failureIf

[lukicdarkoo]

If successIf and failureIf are both true then the node will fail. Likewise, we can have onlyIf and skipIf and give priority to e.g. skipIf. Or maybe even better, throw an exception if both conditions are defined as it can lead to undesired behavior.
