Upgrade System (one by one)

Hi, so right now I have:

UpgradeAmount - Amount of times it's been successfully upgraded (when clicked, if had enough money then do this etc)

Money - The balance

UpButton - The upgrade button, when clicked it'll determine whether or not the player has enough money and will continue if so.

And right now I have it setup like this

___________________________________________________

On touched object "UpButton"__|___System | Set Upgrade to 1

System | Upgrade = 0___________|___Subtract 30 from Money

Money >= 30____________________|

___________________________________________________

On touched object "UpButton"__|___System | Set Upgrade to 2

System | Upgrade = 1___________|___Subtract 100 from Money

Money >= 100____________________|

___________________________________________________

I have it setup like this because I want the upgrades to go 1 by one, however right now if they have enough money for the next upgrade

it buys as many upgrades as it can. How can I stop this?

It's because of Construct's top down structure so every event becomes true for one click if they have enough money. You can add a short wait of 0.1 seconds in, before you set the upgrade variable.

Thank you very much, helped a lot.

You could even wait just 0 seconds [quote:20tpyi4h]One more trick: "Wait 0 seconds" postpones the following actions until the end of the event sheet.

This way you don't even need to really "Wait", because the action is executed in the same tick, but it's the last action that is executed. Anyway, you can look it up here.

You should NOT use Wait for this, just have On touch as the top event, then use sub-events to break down the extra conditions:

On touched object "UpButton"

System | Upgrade = 0

Money >= 30____________________|___System | Set Upgrade to 1

Else

System | Upgrade = 1

Money >= 100____________________|___System | Set Upgrade to 2

blackhornet, in your example you can only do 2 upgrades.

TylerJS, I would do something like this:

On touched object "UpButton"
  Local variable upgradeSuccessful=0

  System | Upgrade = 0 
  Money >= 30           Subtract 30 from Money
                                    Set upgradeSuccessful to 1

  System | Upgrade = 1 
  Money >= 100           Subtract 100 from Money 
                                    Set upgradeSuccessful to 1

  System | Upgrade = 2 
  Money >= 200           Subtract 200 from Money 
                                    Set upgradeSuccessful to 1

  if upgradeSuccessful=1  Add 1 to Upgrade 
  Else  <dispay a message that payer doesn't have enough money>

Also, if you are making the game for touch screen, use On Tap event for buttons.

You can add subsequent Else conditions.

blackhornet , forgot about that, yes you are right.

Here is a shorter version if you're comfortable with using ternary operators:

On Tap on object "UpButton"
  Local variable upgradeCost=0
  upgradeCost = (Upgrade=0 ? 30 : Upgrade=1 ? 100 : Upgrade=2 ? 200 : Upgrade=3 ? 500 : 0)

  if upgradeCost>0 and  Money>=upgradeCost
     Add 1 to Upgrade 
     Subtract upgradeCost from Money

Hey TylerJS!

You should definitely consider storing your upgrade info on an array or string and have just ONE event for upgrading. It would save you a ton of work and is infinitely scalable.

For instance (using string):

upgradeCosts = "30,100,230,500"
currentUpgrade = 0

On Tap on object "UpButton"
Money >= tokenAt(upgradeCosts, currentUpgrade, ",")
        Add 1 to currentUpgrade
        Subtract int(tokenAt(upgradeCosts, currentUpgrade, ",")) from Money

Hope that helps. Cheers!
