Making something arc?

[lunardragon96]

So, I'm working on a game called Grenadier. Now, the idea of the game is that the only weapons are grenades, in surrealistic variations (IE: Ice grenades, Electricity grenades, flashbombs...)
The problem is, I don't know how to make a Movie Clip go in an arc, and the game would suck if grenades just kept going straight. I'm using flash CS4. Help please?

two different ways.

one is to use a motion guide, but i dont like using them as they clutter up my layers.

the second is to make a motion tween of a grenade from start point to end point. then in the middle of the motion tween, make a keyframe and put it in the top of the arc. then do it again putting the grenade in the middle of the two points, again and again until you have a nice arc going

Wait, do I do that in the Grenade MC or the stage?

well since you're doing it in a game, its best to do it in the grenade MC then put stop at the end adding the explosion in the grenade MC

I see...
How do I make it so that if the grenade hits something, it blows up?

[dudejonne]

If it hittest a enemy then delete the grenade and attachmovieclip a explosion to the x and y of the grenade?

[fluffkomix]

well make the explosion an additional MC, then have it inside the grenade animation with stop AS at the end.

then have a hitTest in the enemy that says if it hits the explosion gotoandplay death animation

nvm i was thinking of having the explosion on the ground indefinitely like in a flat level. what the other guy said.

The best way to do it is to use AS. If you make the y higher (i.e., close to the bottom of the flash) then the grenade will fall. Quite simple =o

Aye. Use an xvel, which may or may not be affected by air friction (*0.98 or so) and a yvel, which depends on the launch trajectory but is affected by a variable gravity (generally between +.5 and +2 every frame is a good bet)
