[WORKED] Bullets reducing in HUD when firing a weapon

[ryanjon2040]

Hello everyone...

I made a custom HUD that works but i dont know how to reduce the amount of bullets in my HUD when firing weapon.

Here is the image as it appears in HUD:


When firing my weapon i need each bullet to disappear:


Each of those bullet is a separate image and all of 'em in one Movie Clip. And on each keyframe i modified width parameter for each bullet so that it disappears. Now my doubt is how can i bring it in my game?

bump....anybody??

Sorry, would be easy in Canvas because you would simply tell it to not draw that tile if it's used up already. But I have no clue about Scaleform yet. I suggest you look over the tutorials in the Scaleform section, though, especially the official ones on Youtube.

Doesn't the UDK Scaleform HUD already do this?

They have each bullet in a frame and when a bullet is shot it decrements a counter which lowers to the next frame hiding the bullet.

Another way is to use a mask which simply hides the bullets as you use up ammo.

What TheAgent said ^.

There are a number of ways you can do it, but I think the simplest would be to make a movieclip where the 1st frame has 0 bullets, the 2nd frame has 1 bullet, the 3rd frame has 2 bullets, etc...

Once you've done that you can tell the movieclip to gotoAndStop( ammoCount + 1) every time your ammoCount changes.
So it goes to frame 1 when you have no ammo, frame 2 when you have 1, etc.

Is your max ammo count always the same? You'll need to consider that.
Does the weapon bar look mostly empty when you have a weapon with a max ammo count of 4? What happens if you have a weapon with a max count of 50? You don't want to tell it to go to frame 51 if it doesn't exist (I think flash gracefully handles this by going to the last frame, but it's bad practice to let this happen).

If the bullets are just images, you can just delete the from the frame rather than shrinking them.

Thank you very much for that detailed explanation Captain Zazz

I never thought of it because currently i only have a single weapon. But you are right. Hmmmm....what if i want to implement another weapon?? So if i have another weapon with different ammo capacity how will i update the HUD? Can you please explain this or do you have a link for a tutorial on HUD?
