Legacy GM Making a sprite shake...

[Freedom2Fight]

...using draw_sprite_ext. When the player object gets hurt - that sort of shake.

I have a couple of ideas on how to do this but I need some help.

draw_sprite_ext( sprite, subimg, x, y, xscale, yscale, rot, colour, alpha );

I'm thinking of assigning x and y with variable like shake or wooble. Then I'll write something in the step event that will change the values of shake. I'm thinking of using random functions but I'd prefer it not to be random.

Any help would be appreciated.

draw_sprite_ext( sprite, subimg, x+random_range(-shake,shake), y+random_range(-shake,shake), xscale, yscale, rot, colour, alpha );

Making a sprite shake...

Similar to making a milkshake, but generally involves a bit more blood.

draw_sprite_ext( sprite, subimg, x+random_range(-shake,shake), y+random_range(-shake,shake), xscale, yscale, rot, colour, alpha );

If you want something smoother, use

x + sin(current_time / 1000) *5

This makes it oscillate smoothly side to side.

It will go from center to either extreme, or back again, in 1 second, for a total of a 4 second cycle. To make it faster, reduce the 1000 (current_time is in milliseconds).

sin produces a result from -1 to 1, so multiplying by 5 makes the object move 5 pixels away at the most. Change this number to make it move more or less.

I like this. Thanks, Roderick.

If anyone else have a way of shaking sprites please share. It'll help not just me but also the people who might come across this thread trying to achieve the ..err.. shake.
