Warning: New User
I have a collision detection event between my Player and an Object which plays a sound, adds to the score, and destroys the second object.
How do I actually change the image of the second object, wait 1 second, and then do the destroy event? I can't seem to find a way to make the events work synchronously. This is a major concept I have not been able to figure out.
Your help is appreciated.
If you change the Disappearing animation, you can just have it be the image you want for a second. The Disappearing animation is played for you when you destroy the object, just as the Appearing animation is played when you create it.
This is good and it worked , but what would I use if I wanted to chain a series of events together one after the other? Is there no way to do step 1, when step 1 finishes do step 2, etc.?
You could manually play the animation and when it is over do something else.
I'd use an alterable value - it gives you more flexibility.
eg. Give the object an alterable value called "Delay", with a default value of -1, and then say something like:
+ Player collides with Object
-> Object: Set Delay to 200
+ Always
-> Object: Subtract 1 from Delay
+ Object: Delay = 150
-> Do something...
+ Object: Delay = 100
-> Do something else...
+ Object: Delay = 0
-> Destroy Object
It's pretty easy to calculate exactly what values you need to use.
If your game's framerate is 50fps, a delay of 50 = 1 second. If an object has an animation speed of 50, each game frame will last 50% as long as each animation frame (ie. an "always" event will run twice in the time it takes an animation to change frame once).
Heya.
Pulling up old threads here, but just wondering how to make this happen. How exactly do I "Give the object an alterable value called "Delay"? I'm trying to make this work but I'm lost in the syntax. Greatly appreciated if anyone could give me a break down on how to implement this in MMF2.
Cheers;D
You just click on the object, then in the properties panel select the tab with alterable values. Click add value, it will come up as "alterable value A". Double click to rename it.
Bigfoot,
that helped a lot, thanks. What about the remaining part where it says
"+ Player collides with Object (Ok I know where this is)
-> Object: Set Delay to 200 (I'm lost here...)
+ Always
-> Object: Subtract 1 from Delay
+ Object: Delay = 150
-> Do something...
+ Object: Delay = 100
-> Do something else...
+ Object: Delay = 0
-> Destroy Object"
?
Basically what he means is..
Object is referring to the object with the alterable value that you are setting. Delay obviously being the name of that value. So because you have the "Always Subtract 1 from Alterable Value A(Delay) of Object" each frame it will subtract 1 from it's value. With the collision it sets the value to 200.
So then, when that value hits >200-0 you can set it to do something. Like change animation or something of that nature. In this case what the user wants is a delay before the enemy is destroyed. So with a value of 200, and at an FPS of 60, the delay will be 3.33 seconds.
Hope that makes sense.
knpdude,
thanks for the explanation, appreciate you taking time to explain it. But how do I actually apply this in MMF2 to my project? Such as "go here, click this object, type this...". Maybe i'm getting confused in the mechanics and steps (ok not maybe, for sure).
In the events editor, you can set alterable values of an object. Right click the object in question, and it's under 'Alterable values -> Set'
The list that pops up is the letters A-Z, which isn't so convenient. You can rename these names to something else, in the properties panel when you click on an object in the frame editor. You will likely want to rename "Alterable Value A" to "Delay"....
Alterable values are simply internal variables that every object has. Your given a bunch of them with default names. Its best for your sanity to rename them....
You can also test these alterable values in a condition. Create a new event, and right click the object in the popup window. You can determine if any alterable value equals, or is greater or less than some value.
Ask away if any of this is still unclear. Good luck!
Kinase,
thanks for the reply and the willingness to help me on this! I apologize ahead of time for being rather "thick", but most times I'll understand the process best once I actually see it in action. How would I do this "+ Player collides with Object
-> Object: Set Delay to 200"?
I see my object (a chunk of "grass"). I see the line in the box that says "Collision beetwen [object:pig] and [object;grass]" and right click the grass object...and then what? I don't know how to execute it to get those following lines (and don't know code, I'm sure if I did this would all make more sense!)
Got it. I did not fully understand the steps I needed to take in order to create the expressions ;). No way really I could of known, but now that I do, its all starting to make a lot of sense! Love it! Thanks everyone for chipping in your opinion and guidance, its truly appreciated!
Blacstar, Here's an example: Look in the event editor to see how it's done. Line # 5 you can adjust the value (delay) up or down to destroy the object. Right now I have it set you 160 because the fuse on the dynamite animation matches it,.but you can also change the speed of the fuse animation up or down to match the delayed value,.(explosion)
I just want to clear this up a bit. I think the confusion is in the name "delay". The alterable value (name) of any object is set by default, A, B, C, D and so on. Referring to the name "Delay" is just it's Alterable value A being changed (it's name) to "Delay". That's all that means. I am so used to using the default's of the names in my games I don't bother changing them,.but that's just me and something I'm use to. Download this example and click on it to open in MMF. Hope this helps to clear things up a bit. Space bar to shoot! Shoot the dynamite at the blocks. Press F2 to end the application.

Smanman your the best brother, appreciate the help on this!
You're welcome! Sometimes it's better just to look at an example rather than having it explained. There are other ways to do this also, but this is a simple way and I use this a lot in my game for delays.Quote:

To clean up my other post: I meant to say,.. The alterable value (name) of any ACTIVE any other objects is set by default, A, B, C, D and so on.
