change animaton and speed

[discocar]

so I have an item and when the npc collects the item it will change its animation and speed.

at the moment the NPCs ai is like this

case 1:
// move right
image_xscale=1;
image_speed = 0.1;
sprite_index=sprite20;
speed = 1;
direction = 0;
move_hold = 1;
break;
case 2:
// move left
image_xscale=-1;
image_speed = 0.1;
sprite_index=sprite21;
speed = 1;
direction = 180;
move_hold = 1;
break;

when the npc collects the item to increase its speed I would need to do something like npc collides with the item

speed += 2

but how would I go about changing the sprite animation?

Thanks

sprite_index controls the sprite of the instance. If you add an extra check that tells you whether the NPC picked up the item or not, you can assign the correct sprite accordingly.

Or is that not what you meant? If it isn't, I'm unsure what you mean by "changing the sprite animation".

you could change the sprite_index to a running sprite or change increase image_speed depending on what result you are going for.
