[GM] changing graphics while running

[fadark]

i'v seen that in other people's games, the player changes graphics while running.
can someone tell me how to do this?

[Arrow]

Absolutely, but you'll need to better outline what it is exactly. Do you mean running as opposed to walking, or running as in basic movement in a given direction?

[fadark]

running as in basic movement in a given direction? (as opposed to standing still)

[Arrow]

Ah, thats simple enough. Make it so when a movement key is pressed (not held, pressed) the sprite is changed accordingly. When it is released, change it back.

[fadark]

oh! i overlooked that. i didnt think it was so simple. thanks man!

[edit]
wait, that's not what i meant. i dont want a running sprite. i want a running sprite animation.
in other words:
i want my character to move his legs (like in the legend of zelda platformer)

can you tell me how to do that?

[firerain]

Just move his legs and have no motion? Then remove the motion...

[fadark]

thats not what i mean. i want him to move his legs and have motion. i have heard something about subimages but im not completely sure what they are. what are they?

Look through the sticky full of examples I stopped updating for some reason. In there you should find one called FoxNL's Platform example. (or whatever it's called, I know it had Fox somewhere in it) That should answer all of your questions.

ok, thanks! but i have one more question.
can someone give me the expressions (that can be used in the "Test Experssion" event) that:

-test weather the player is moving left
-test weather the player is moving right
-test weather the player is not moving to the left or right (but might be moving up or down)
-test weather the player is in the air

-hspeed<0
-hspeed>0
-hspeed=0
-place_free(x,y+2)

[fadark]

wow! you're either an expert game maker, or im a newb game maker (which i am)..... or both..... lol! thanks!

[Arrow]

lol, not quite expert I don't think, I still ask a dumb question or two myself every now and then. That wasn't a dumb question though, it's good you asked it. So you know, you can use basic math symbols, like +, -, *, (multiplication) or / (division) in almost any kind of mathematic formula in GM. For instance, if you wanted to make an object move at half the player's current hspeed, you would say:

self.hspeed=player.hspeed/2
