For ex:
onActivate > self > addVariable > brick > chops > 1
onActivate > self > ifVariable > brick > chops > greaterEquals > 5
onVariableTrue > self > setVariable > brick > chops > 0
onVariableTrue > client > addVariable > Logs > 1
onVariableTrue > client > centerPrint > You chop down the tree!
onVariableTrue > self dissapear > 10
onVariableFalse > client > centerPrint > You chop at the tree!
What this would do is, every time that tree is clicked it adds its own 'Chops' variable. When that variable reaches 5 or greater it would set its own chops to 0, give you a variable, dissapear, and tell you you chopped down the tree. If you click the tree and it HASN'T reached 5 or greater then it would say 'You chop at the tree!'
