Since we want a random character returned, we use the random expression with the length of the 'rand'-string as parameter. The confusing thing is the second parameter, the start index. Which actually means we set the current value of the array to:Ĭompare it to the example above, you will see that it isn't really complicated. So we use this expression to return one random character of the 'rand'-string. The first parameter of the expression is the string, the second the starting index of the part and the third parameter is the number of characters you want returned. So for example, if you had a string "ScirraConstructTwo", the expression ![]() The 'mid'-expression can return any part of a string. To do this effectively it is vital to learn about another expression: 'mid'. Global variables will be seen throughout the entire game. Variables can be seen in different places. Clicking on the Add event icon will let you add a variable: There are two types of variables in Construct 2: global and local variables. Some expressions of the array object come in handy here: 'Array.at', which returns the array value at any given XYZ index, and Array.CurX/CurY, which return the indices being currently looped.Īfter these checks we write the actual value to the array in a new sub-event, which will be randomized from the remaining possibilities. To add a variable, go to your event sheet and right-click on it. Then, as mentioned above, the last two elements will be match-checked. One is there to check if the X/Y array index is greater than 1, cause there can't be two lower indices if it isn't. Note that the conditions here are actually all the 'Compare two values'-condition of the 'System'-object. ![]()
